3. Can't get jsreport to run using jsreport start

Can't get jsreport to run using jsreport start


  • Hurrah! Thanks!
    /node_modules/.bin/jsreport file properly formatted for easier reading:

    ok, at this point i'm not sure how you end with all of these errors, so i think the best here will be that somehow i connect to your server and check the error by myself.

    if you are able to share with me a temporal user of your server, i will try to start a ssh session and connect to your server, and try the commands directly and see what i can do about it. you can send me those details at bjrmatos@gmail.com

  • Unfortunately our security won't allow me to let anyone connect to our severs.
    I guess I'll have to stick with using this, even tho I'm not sure why nothing else works.

    node node_modules/jsreport --init
npm start

    I still have to connect this with our Angular app, so let's hope that doesn't cause more weird problems.

    Could you explain a few of the installed installed files to me?
    The docs say that jsreport.config.json is created and loaded, but that dev.config.json or prod.config.json are loaded too depending on the NODE_ENV variable.
    So does that mean BOTH jsreport.config.json AND either dev.config.json or prod.config.json are loaded together, or just one of the 3 depending on what settings are defined? Also where is NODE_ENV defined? What file?

    If I look in package.json, I see a scripts section:

    "scripts": {
    "start": "node server",
    "jsreport": "jsreport"
  },

    Doesn't this mean I should be able to run these as commands like start jsreport and that would actually run node server jsreport? Because if I run node server jsreport it runs but WITHOUT my reconfigured port number (4201 over the current default), but if I run start jsreport, it says no command found?

    yes, you should be able to start jsreport with just node server.js instead of jsreport start. there is no difference. the reason that you don't have the correct right port probably is because you don't have a dev.config.json file in your project, maybe it is called jsreport.config.json in your case (explanation bellow for why jsreport.config.json is not loaded for your project), you need to rename jsreport.config.json to dev.config.json

    Could you explain a few of the installed installed files to me?

    yes, of course. first of all the docs that you see right now are mostly relevant for jsreport v2, they are updated to reflect latest version of jsreport (v2), we want in future to have a way to inspect docs for older versions (like your case, since you are using jsreport v1), but right now is not possible because it requires some internal work that we are not able to find the right time to do it.

    The docs say that jsreport.config.json is created and loaded, but that dev.config.json or prod.config.json are loaded too depending on the NODE_ENV variable.
    So does that mean BOTH jsreport.config.json AND either dev.config.json or prod.config.json are loaded together, or just one of the 3 depending on what settings are defined?

    just one file is loaded, you can see what file is loaded in first line of the logs of your console, it will be something like this (in case of there is no config file it will print dev.config.json):

    info: Initializing jsreport@1.6.0 in development mode using configuration file dev.config.json

    in your case since you are using old version (jsreport 1.6.0 ), the jsreport.config.json is not supported there (it will never be loaded for your project), so only one of the files (dev.config.json or prod.config.json) will be loaded, by default what is loaded in your case is dev.config.json if present, the prod.config.json is just loaded when the environtment variable NODE_ENV is set to the value production

    Also where is NODE_ENV defined? What file?

    the NODE_ENV is an environtment variable, in linux you can set environtment variables by using the following syntax in your command when starting jsreport: NODE_ENV=production node server.js, for other different OS you can find a lot of answers by searching "how to set environtment variables in ..." (remember that if you don't define the NODE_ENV env var then what is loaded by default is dev.config.json)

    to add more about this, make sure you are not using new config format (what you see in current docs is the format of configuration for v2), since you are using jsreport 1.6.0 then the configuration is a little bit different, keys has other names or different shape, etc. an example of an old configuration for jsreport 1.6.0 is like this:

    {
  "httpPort": 5488,
  "authentication": {
    "cookieSession": {
      "secret": "<your strong secret here>"
    },
    "admin": {
      "username": "admin",
      "password": "password"
    },
    "enabled": false
  },
  "connectionString": {
    "name": "fs"
  },
  "logger": {
    "providerName": "winston"
  },
  "blobStorage": "fileSystem",
  "tasks": {
    "allowedModules": "*",
    "strategy": "http-server",
    "timeout": 10000

  "scripts": {
    "allowedModules": "*",

    "searchOnDiskIfNotFoundInStore": true
  },
  "phantom": {

  • Thanks for the clarification, that clears a couple things up a bit.
    I'm following the files on Dev as close as possible trying to keep Prod as close to Dev (which works fine) as possible, so I'm following its config format and only deviating when something doesn't work as expected.

    I'm glad that running node server.js works for me, but do you have any ideas as to why trying to run the scripts in the package.json file don't work? Is this the same probable that we've been trying to debug or a different issue? I guess this means I can't write any of my own scripts there either then if it can't seem to find them.

    but do you have any ideas as to why trying to run the scripts in the package.json file don't work?

    reading your old comment, your first script "start": "node server",, should be running with npm start, it will do the same that running node server.js if running npm start does not work then probably it is the same error that we were trying to debug.

    your second script "jsreport": "jsreport" should be running with npm run jsreport, but that probably will give you an error that is related to the same error that we were trying to debug.

  • So running either node server.js or npm start both work and do the same thing... without my customized port. I do have a prod.config.json defined, so if I run npm start --production then it runs with the correct port.

    Running npm run jsreport gives me an error:

    I'm assuming given what we've assessed so far this is not surprising?

    ok, you can also do node server.js --httpPort 4201 in case you want to use another port but dont want to edit your config file when trying multiple different ports.

    yes, exactly. it is still a mystery for me too

  • Thanks for your help so far. I really appreciate it.

  • Is there a way to define in server.js which config it should use? Either dev.config.json or prod.config.json?

    0
  • administrators

    i think the only way to do it in the version of jsreport you have (1.6.0) is by adding the following line at the top of your server.js file

    process.env.NODE_ENV='development' // this will make it use dev.config.json
// process.env.NODE_ENV='production' // this will make it use prod.config.json

  • Or read file manually in server.js and pass it to jsreport :)

    const jsreport = require('jsreport')(JSON.parse(fs.readFileSync('myconfig.json').toString())

  • This first option worked great =)
    My issue was/is that I have a PM2 server watching to make sure jsreport doesn't go down, but when I tell pm2 to start my server.js file, everything starts up but it doesn't seem to pick my my prod.config.json, so it was running on the wrong port and lost the rest of my config options. It didn't seem to be picking up either of configs.. because both my dev and prod config files define my port as 4201.. but it started on the default port of 5488.

  • Any idea why last week I my Angular app was connecting to jsreport and generating PDFs fine, and now I check it today and when I try to render a report I get this error:
    "Error during rendering report: Unexpected end of JSON input"

    I haven't made any changes to it since since it last worked.

  • Currently we have a bug that can cause inconsistency in underlying data in some edge cases.
    Please try to backup/remove files in the root of the data folder and start again.
    Usually the inconsistency is in the settings file which anyway contains just some logs.

    0

  • Ah sorry. I didn't read it carefully. The bug I was mentioning is in v2 and would produce different error. Please ignore previous comment. :)

  • I just tried our Dev server (my other post was for our Prod server) and I'm getting the same error there. Dev has been working fine for months.
    Any hints as to where to look exactly for what might be causing this issue suddenly?

  • Try to give us full output, it should be also in logs.

    hmm does this happens too if you open jsreport studio and try to render something? (it is just some check to see that there is no jsreport entity corrupted) so far it looks to me that this is caused by sending some bad json from your angular app, a quick check can be to try to render something from studio, if it works there then probably your angular app is sending bad data in some case.
