Protocol error (Page.printToPDF): PrintToPDF is not implemented

lapinskyi98

Hello! I have some problem with PrintToPDF!

import request from 'request'

const chromium = require('chrome-aws-lambda')
const JsReport = require('jsreport')

const promisify = require('util').promisify
const ncp = promisify(require('ncp'))
const path = require('path')
const fs = require('fs')
const AWS = require('aws-sdk')

export default async(_, {event}, ctx) =>{
let jsreport

const init = (async () => { 
	jsreport = JsReport({
		//configFile: path.join(__dirname, './prod.config.json'),        
		chrome: {
			launchOptions: {
				args: chromium.args,
				defaultViewport: chromium.defaultViewport,
				executablePath: await chromium.executablePath,
				headless: chromium.headless,
			}         
		}
	})
	//await ncp(path.join(__dirname, './data'), './tmp/data')
	return jsreport.init()

})()
const body = {
	'template': {
		'name': 'invoice-main',
		'recipe': 'chrome-pdf'
	},
	'data': {
		'data':[
			{
				'customerNr': 1,
				'salutation': 2,
				'nameCustomer': 2,
				'additive': 2,
				'street': 2,
				'postCode': 2,
				'city': 2
			}
		]
	}
}
//start
await init
//errr
const res = await jsreport.render(body)
console.log(res)
const response = {
	statusCode: 200,
	body: null,
}

return response }

it*s my code resolver.
After call I have err -

      }
    }
  ],
  "data": {
    "reports": {
      "test": null
    }
  }
}

Maybe it's because of the different version of puppeteer bundled in jsreport and chrome you use from chrome-aws-lambda package you use.
Please try to follow our aws lambda tutorial https://jsreport.net/learn/aws-lambda-serverless

I found a solution

await JsReport({
			//configFile: path.join(__dirname, './prod.config.json'),        
			chrome: {
				launchOptions: {
					args: chromium.args,
					defaultViewport: chromium.defaultViewport,
					executablePath: await chromium.executablePath,
					headless: true,
				}         
			},

----> headless: true
