Puppeteer - Error: Protocol error (Network.getResponseBody): No resource with given identifier found

Question

I'm trying with this code to get the response body from a website using puppeteer.

#!/usr/bin/env node

require('dotenv').config();
const puppeteer = require('puppeteer');
const readline = require('readline').createInterface({
    input: process.stdin,
    output: process.stdout
});
const path = require('path');
const fs = require('fs');

//
console.log('Starting Puppeteer...');

let responseBody = [];

(async () => {
    const browser = await puppeteer.launch({
        headless: false,
        executablePath: '/Applications/Google Chrome.app/Contents/MacOS/Google Chrome'
    });
    const page = await browser.newPage();
    
    await page.setRequestInterception(true);

    page.on('request', (request) => {
        request.continue();
    });

    //
    page.on('requestfinished', async (request) => {
        const response =  await request.response();
        const url = response.url();
        // store chunks url
        if( url.startsWith('https://audio-akp-quic-control-examplecdn-com.akamaized.net/audio/') ){
            console.log(await response.buffer());
            //responseBody.push(response.buffer());
        }
    });

    //
    await page.goto('https://accounts.examplecdn.com/login', {
        waitUntil: ['load', 'networkidle2']
    });

    const emailField = await page.waitForSelector('#login-username', {timeout: 3000});
    await emailField.type(process.env.EMAIL, {delay: 100});

    const passwordField = await page.waitForSelector('#login-password', {timeout: 3000});
    await passwordField.type(process.env.PASSWORD, {delay: 100});

    const submitButton = await page.waitForSelector('#login-button', {timeout: 3000});
    await submitButton.click();
    
    //
    const navigation = await page.waitForNavigation({ waitUntil: ['load', 'networkidle2'] });
    
    //if( navigation.url().endsWith('status') ){
    await page.goto('https://example.cdn.com/search', { 
        waitUntil: ['load', 'networkidle2'] 
    }).then( async (response) => {
        //console.log(response);
        const cookieButton = await page.$('#onetrust-accept-btn-handler');
        await cookieButton.click();
        const searchField = await page.$('[data-testid="search-input"]');
        await readline.question('What track do you want to search for?', (input) => {
            console.log('answer:', input);
            searchField.type(input).then( async () => {
                await page.waitForXPath('//*[@id="searchPage"]/div/div/section[1]/div[2]/div/div/div/div[4]').then( async (element) => {
                    element.focus().then( async () => {
                        // //*[@id="searchPage"]/div/div/section[1]/div[2]/div/div/div/div[3]/button
                        const playButton = await page.waitForXPath('//*[@id="searchPage"]/div/div/section[1]/div[2]/div/div/div/div[3]/button');
                        await playButton.click();
                    });
                });
            });
        });
    });
    
    
    //}

})();

I'm having problem with it and this error will be logged and the script will terminate.

I need to collect all the response body content when a certain url is called, then using ffmpeg I want to convert it back to a full length track. How I can solve the problem? Is it possible to get the response body of each request and then join all together?

Answer 1

The error No resource with given identifier found will happen when the page navigated to another URL before you complete getting the content of network response. It should be caused by redirecting, JS history API, and so on.

Thus, you can do either:

• Stop browser to move to other pages before the response is processed.
• Use Firefox. Firefox doesn't have this issue and Chrome team won't fix the issue.
