3. Nested requests using request-promise: how to do it?

Nested requests using request-promise: how to do it?

  • R

    Below is a simplified version of my code. The outer request works. The inner one produces an error that a promise was created but not returned. I thought I was returning OK.

    const fs = require('fs');
const request = require('request-promise');
let theBaseURL = "https://pharmacyinformatics.local:3000/v1";

function beforeRender(req, res, done) {
    let wbcPath = '/inpatient/culturesWbcNA/1/'
    let patientList = []
   
request({
        url: theBaseURL + "/inpatient/patientsNA/" + facilityQ,//ignore this; it is set elsewhere
        method: "GET",
        json: true,
        strictSSL: false,
        headers: {
            'User-Agent': 'Super Agent/0.0.1',
            'content-type': 'application/json'
        }
    }).then(results => {
        req.data.patients = results;
        
        for (let patient in req.data.patients) {
          patientList.push(req.data.patients[patient].visits[0].p3_csn.trim());
        }

        if (patientList.length === 0) {
          done();
        }
        
        let patientStr = '';
        req.data.wbc = [];
        let wbcCount = patientList.length;
        
        patientList.forEach((el, done) => {
            let loopWbcPath = wbcPath + 'lr_csn=' + el;
            
            console.log('loopWbcPath', loopWbcPath);
            
            request({
                url: theBaseURL + loopWbcPath,
                method: "GET",
                json: true,
                strictSSL: false,
                headers: {
                    'User-Agent': 'Super Agent/0.0.1',
                    'content-type': 'application/json'
                }
            }).then(resWbc => {
                let wbc = {}
                wbc.csn = el;
                wbc.data = bodyWbc.data[0].lab_results;
                wbcCount -= 1
                
                req.data.wbc[wbc.csn] = wbc.data;
            
                if (wbcCount === 0){
                    done();
                } else {
                    return
                }
            }).catch(errWbc => {
                console.log('err', errWbc);
            })
        })
    }).catch(function(err) {
        console.log('err', err);
    })

    a promise was created but not returned

    well that sounds like a warning that everyone gets when mixing callback based code (the beforeRender) with promises.

    FYI since jsreport v2 we added support for promises inside the beforeRender/afterRender functions, so your code can be refactored to this:

    const fs = require('fs');
const request = require('request-promise');
let theBaseURL = "https://pharmacyinformatics.local:3000/v1";

async function beforeRender(req, res) {
  let wbcPath = '/inpatient/culturesWbcNA/1/'
  let patientList = []

  try {
    const results = await request({
        url: theBaseURL + "/inpatient/patientsNA/" + facilityQ,//ignore this; it is set elsewhere
        method: "GET",
        json: true,
        strictSSL: false,
        headers: {
            'User-Agent': 'Super Agent/0.0.1',
            'content-type': 'application/json'
        }
    })

    req.data.patients = results;
    
    for (let patient in req.data.patients) {
      patientList.push(req.data.patients[patient].visits[0].p3_csn.trim());
    }

    if (patientList.length === 0) {
      return 
    }
    
    let patientStr = '';
    req.data.wbc = [];

    await Promise.all(patientList.map(async (el) => {
        let loopWbcPath = wbcPath + 'lr_csn=' + el;
        
        console.log('loopWbcPath', loopWbcPath);

        const resWbc = await request({
            url: theBaseURL + loopWbcPath,
            method: "GET",
            json: true,
            strictSSL: false,
            headers: {
                'User-Agent': 'Super Agent/0.0.1',
                'content-type': 'application/json'
            }
        })

        let wbc = {}
        wbc.csn = el;
        wbc.data = bodyWbc.data[0].lab_results;
        
        req.data.wbc[wbc.csn] = wbc.data;
    })
  } catch (e) {
    console.error('Error', err)
  }
}

    however that code contains a variable called bodyWbc that i don't see where it is defined, so make sure to review that code

    So, As I've tried to understand such things as Promise.all and other options for looping promises together, I encountered a very strange bug. At least I think it's a bug in jsreport. The first code below works. The second does not. There's only one line different. Why won't a foreach in there work? I found this as I was trying to reduce my code to the minimum working and then introduce what I need to build the Promise.all. Obviously, I need a foreach or for to build an array of promises. But I can't even get a regular foreach to work. See the arrows below pointing out the change.

    const fs = require('fs');
const request = require('request-promise');
let theBaseURL = "https://pharmacyinformatics.local:3000/v1";

function beforeRender(req, res, done) {
    let wbcPath = '/inpatient/culturesWbcNA/1/'
    let patientList = []
    
    let facilityQ = 'p3_facility=CVLB';
    console.log('options', req.options);
    
    if (typeof req.options != 'undefined') {
        if (typeof req.options.facility != 'undefined') {
            facilityQ = 'p3_facility=' + req.options.facility;
        }
    }
    
    request({
        url: theBaseURL + "/inpatient/patientsNA/" + facilityQ,
        method: "GET",
        json: true,
        strictSSL: false,
        headers: {
            'User-Agent': 'Super Agent/0.0.1',
            'content-type': 'application/json'
        }
    }).then(results => {
        console.log('results', results);
        req.data.patients = results;
        
        for (let patient in results) {
          patientList.push(results[patient].visits[0].p3_csn.trim());
        }

        if (patientList.length === 0) {
          done();
        }
        
        let patientStr = '';
        req.data.wbc = [];
        let wbcCount = patientList.length;

    BTW, the error is that the request times out. See error message below. It's as if the

    return done();

    never gets run when there's a foreach in there.

    ok interesting, what jsreport version do you have?

    are you really sure that the server at https://pharmacyinformatics.local:3000/v1 is processing the requests? i mean, that you are sure that server is not getting stuck and not responding. i will try to replicate the issue with the same script but replacing the request to external server with a mock

    0
  • R

    I'm using 2.4.0 due to the integration issue with 2.5.1 I noted in another thread. So my instance of jsreport lives inside the same server app that's returning the data. I use WebStorm as my IDE and in the log there, I see that the initial request is performed, which gets the patients. Then follows two Winston logs. The first confirms that the patients were returned. The second is a status 200. So up to that point we're good.

    However, I would have expected to see the console.logs I have in the code, namely:

    console.log('results', results);
console.log('patientList', patientList);

    But I don't see these either in the IDE or the 'debug' output in the report builder.

    Anyway, in the IDE, it then hangs and I see the error messages generated by jsreports which I pasted in my last message. I'd paste the whole IDE log here, but there's actual patient info, so I can't. I suppose I could scrub it, but I don't think it would add anything to what I've already said.

    Immediately after the jsreports errors I do see one more Winston error which says

     Error during processing request at https://pharmacyinformatics.local:3000/reporting/api/report/ActiveAntibioticsHTML

    That's the report I'm trying to run.

    I have about 100 reports that follow a similar pattern to the one I'm trying to get working as my test of jsreports. So if I can just get this one to work, I should have a good pattern to follow and that will allow us to move forward with jsreports rather than having to look elsewhere for a solution. I appreciate how responsive you've been so far with a tester (i.e. non-paying customer yet). Thanks.

    FYI, this was the thread where I reverted to 2.4.0: https://forum.jsreport.net/topic/1090/integration-into-existing-express-application-error

    One more note: I see when I remove that one line with the foreach that immediately after the status 200 log message in the IDE that the console.logs from my function show up like they should. So I'd say the hangup is in the beforeRender function.

    But I just now saw that you also replied to my first post here. I think you were writing at the same time I was writing my second post here, so I'll go check out what you said and see if I can incorporate that. Looks like you said there is a new promise version of beforeRender instead of the callback version. Is it in 2.4.0? I guess I'll find out in a few minutes. I think I'll go eat lunch first, though.

    yes, this is supported since 2.0.0

    i will try now to replicate your bug in 2.4.0, but i think that bug is not present in 2.5.0. i will confirm this.

    FYI, this was the thread where I reverted to 2.4.0

    yes, i remember you had problems integrating into express, and we found solution for it that needed that you installed the fix from repository using npm i jsreport/jsreport-studio but then you were getting more errors. i did not have the chance yet to check deeper but i'm thinking that the rest of your problems were related to the fact that you are adding jsreport express app after the middlewares of your app and that the jsreport express app works standalone (it has its own set of middleware), i tried to explain it to you here in this comment but probably the idea was not clear. so i will take the chance to show you with the same code that you posted originally.

    to understand what was changed search for the string HERE IS THE ONLY CHANGE, BUT THIS CHANGE IS BIG in the above code, if you change your code to this and you have installed the fix we mentioned here i'm almost sure that there should be no other problem.

    now i'll try to confirm that the bug that you found in scripts is not present in 2.5.0...

    actually it is not a bug in jsreport, the error is just in your code, here is the problematic line:

    patientList.foreach(el => {console.log('el', el);})//<<<<<<<<<<<<<<<<<<<<<<<<This is the only change. Breaks the code.

    the right code is

    patientList.forEach(el => {console.log('el', el);})//<<<<<<<<<<<<<<<<<<<<<<<<This is the only change. Breaks the code.

    it is just a typo foreach -> forEach

    you see the render hanging because that typo, you can make the error more visible if you modify your catch handler to this:

    }).catch(function(err) {
        console.log('err', err);
        // this makes sure that the script is finished, but with error, and the render does not hang
        // callback based code is always hard to manage, so if possible try to switch to the `async/await` syntax that i shared with you
        done(err)
})

    Oh for Pete's sake! Typos!!!

    "E"

    I should have copy/pasted into my IDE. I'm sure it would have caught it. FYI, I have moved where I had jsreport added to my index file so as to avoid my other middleware per your suggestion. That worked fine. I suppose I should try 2.5 again once I take a break - maybe after I finish this report.

    I also began incorporating your suggestion to use async/await and so far that looks good. I have a couple more things to check and then add in, but I think I understand it now. Again, I appreciate your help and patience.

    haha that happens to everyone.

    sure, i just wanted to show you that there should be no weird problems when integrating jsreport with express, just relax and when your report is ready you can give jsreport 2.5.0 another try.

    awesome, no problem! good luck with that!
