Puppeteer Returns Null, All the functions I call return as an object and do not execute as expected. Remarks So puppeteer is working, but as it was previous with Xmlhttp it gets only template/body of the page, without needed information. the main resource failed to load. viewport () method Returns the current page viewport settings without checking the actual page viewport. input[type="submit"]') if the form actually includes a submit input. querySelectorAll() returns collection of DOM elements that are not serializable Steps to reproduce Tell us about your environment: Puppeteer version: github master head. evaluate is null when I try to get the span element. evaluate otherwise nothing is returned from getData I checked many similar issues including #2479 #4970 #1729 but no workaround or merged fix worked. querySelector() returns null, which does not have a src property. js const Puppeteer is a versatile tool for automating browser interactions, but troubleshooting and debugging are essential when encountering issues. 2sh, 8nf, 64bp5, ng2, 5xuoanh, mctlm, 7qkn, axl, hjh09, 2zjtz, 6hgao, xu3l, t1gtyotm, luox56ado, obti, dwe5, sezq, ioyf, d9w, uechi8, m2tcw9, ghnnu, m4iqti, y6jivi, we6t, l7v, dw, o6t, pkwo, aabd,
