Javascript – Error read properties of undefined (reading 'CallCollection')

I have an error when starting my bot using puppeteer and whatsapp-web.js, when starting it gives the error:

Error: Evaluation failed: TypeError: Cannot read properties of undefined (reading 'CallCollection')
    at __puppeteer_evaluation_script__:9:66
    at ExecutionContext._evaluateInternal (C:Users103182DocumentsBotCargas2node_modulespuppeteerlibcjspuppeteercommonExecutionContext.js:221:19)
    at processTicksAndRejections (node:internal/process/task_queues:96:5)
    at async ExecutionContext.evaluate (C:Users103182DocumentsBotCargas2node_modulespuppeteerlibcjspuppeteercommonExecutionContext.js:110:16)
    at async Client.initialize (C:Users103182DocumentsBotCargas2node_moduleswhatsapp-web.jssrcClient.js:278:9)
    at async C:Users103182DocumentsBotCargas2bot.js:231:5

Does anyone know of a solution for this?

I already reinstalled puppeteer, node modules, and also whatsapp-web.js but the error still persists.

    Same here! Since some hours ago…

    My code is the same of last weeks but error occurs today without any changes.

    I didn’t find anything else on the web so it might be a new bug due to some whatsapp update still not handled by whatsapp-web.js (my actual version is 1.21.0, the last one available)?

    Updating to version 1.21.1-alpha.1 is working again.
    I found the solution suggested by a user on GitHub.
