Hello.

jsreport.afterRenderListeners.add('someName', async (req, res) => {
    console.log("TEST")
    afterRender(req,res)
})
async function afterRender (req, res) {    
    console.log(res.content)
}

i push a line console.log("TEST") in this function and it's show 4 times when i generate a report. What happen ? (I use some background, footer, header,... )

I try

const jsreport = require('jsreport')()

jsreport.afterRenderListeners.add('someName', async (req, res) => {
    console.log("HAHAHA")
    afterRender(req,res)
})
async function afterRender (req, res) {    
    // here use extra code to check if res.content is valid
    if (Math.random() > 0.5) {
        // its ok
        return
    }

    //retry
    const retryRes = await require('jsreport-proxy').render({...req})
    res.content = retryRes.content
}
if (process.env.JSREPORT_CLI) {
  // export jsreport instance to make it possible to use jsreport-cli
  module.exports = jsreport
} else {
  jsreport.init().then(() => {
	console.log("JSreport POWERFUL!")
    // running
  }).catch((e) => {
    // error during startup
    console.error(e.stack)
    process.exit(1)
  })
}

But it told me that: "Can not find jsreport-proxy module" ?

Where is the list event listenner i can use ? Example: afterRenderListeners ?

Can i throw error to client if i detect error font ?

yes it happens randomly but not because of pdf-parse but i use pdf-parse to read the text in pdf to confirm that there is no font error i will return it to client and if font error i will output the pdf again As long as there is no font error, that's it.

[QUESTION]
jsreport.afterRenderListeners.add('someName', async (req, res) => {
console.log(res.content)
})
how can i use check pdf-parse in this. and when successful, I return the client and if not successful I will generate the PDF again?

Hello i create a server to generate PDF
const jsreport = require('jsreport')()

But sometime PDF generate with error fonts (I try to find problem but still dont know why). So I use pdf-parse to validate if fonts error. But i use it from client. The problem is I have more than 1 client so i want use pdf-parse from server before send PDF to client.

Is there any way to do that ?

any idea ?

It look like only happen on "accented letters". And another interesting thing is that it just happens randomly. As you can see in the picture, there are places that are faulty, there are places that are not

I exact font in file PDF and got below

No. I can't. I dont know how to reproduce that to fix.

I only know that it's not frequently happen. Randomly.
