Thank you for sharing.
I have a problem though. My document is made up of a main template and a header-footer template that I merge with PDF-Utils (in the GUI).
Using this snippet of code I have the correct number of pages, and on the second set of pages I have a watermark but I lose the header/footer..

Any idea? Maybe because the GUI pdfUtils is run after render?
in any case I've tried to programmatically read the template and merge it and then merge over the watermark, but I don't seem to be able..

const jsreport = require('jsreport-proxy')
async function afterRender(req, res) {

//this is the watermark
    const duplicateRes = await jsreport.render({
        template: {
            name: 'watermark' 
        }   
    })

    const $pdf = await jsreport.pdfUtils.parse(res.content)
    const pagesToMerge = new Array($pdf.pages.length).fill(duplicateRes.content)

    const originalBuffer = Buffer.from(res.content)  

    //now add header-footer
    const corniceRes = await jsreport.render({template: {name: 'header_footer' }})

    const pagesToMergeCornice = new Array($pdf.pages.length).fill(corniceRes.content)

    const corniceBuffer =  await jsreport.pdfUtils.merge(originalBuffer, pagesToMergeCornice)

    // 

    const withDuplicateBuffer = await jsreport.pdfUtils.merge(corniceBuffer, pagesToMerge)
    res.content = await jsreport.pdfUtils.append(res.content, withDuplicateBuffer)
}

Thanks

Ok, as I suspected the problem was with the huge headers.
Since the same problem was in Postman, we solved it with the same workaround:

NODE_OPTIONS=--max-http-header-size=16384 jsreport start

this is the original post [https://github.com/postmanlabs/postman-app-support/issues/8656]

Hello,
I'm experimenting with calling an external API from a script.
I have two APIs on a local server: one can be called from JSReport, the other throws a cryptic error.

const axios = require('axios'); 
 
async function callApi() {
    return axios.get('http://localhost:8800/api/PING.PING?noblock');
}
 // add jsreport hook which modifies the report input data
async function beforeRender(req, res) {
    const r = await callApi();
    console.log("ret is ",r.data)
    req.data = { ...req.data, ...r.data}
}

while if I change it to a login API with post method:

const axios = require('axios'); 
 
async function callApi() { 
    return axios.post('http://localhost:8800/api/REST_ACCOUNT.LOGIN',{
          Usercode:"000000",
          Codice_Concessione:"GG",
          Browser:"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/85.0.4183.121 Safari/537.36",
           Password:"xxxxxxxxxx",
           Lingua:"POR"
         }
    ); 
}

i get this error

I've tested calling the latter API on a browser page with the same Axios code and the params are correct.
The only unusual things in this API are:

• return data is a 9K json
• response headers are pretty big, around 12K because of the JWT token

Any ideas?
Thanks
