Whatsapp-web.js: Found Errors After Updating WhatsApp

[syahrulright]

I encountered an error after updating WhatsApp to version 2.20.202.18.
The error is like this:

UnhandledPromiseRejectionWarning: Error: Evaluation failed: Error: MsgKey error: don't have a matching constructor

SAME

It seems that WhatsApp improved their security or made changes to their code structure.
How do you think about this?

My code still working well. I run from some weeks ago.

Maybe the problem comes in the new version of Whatsapp Web.

Do you have to do anything besides updating the package? I did it but it's still not working here

WhatsApp web released an update last night that caused this issue, but I immediately addressed it and released the new version. Please make sure you are running v1.11.0. Any other version will not work.

Check by running this:

client.on('ready', async () =>{
    console.log("WhatsApp Web v", await client.getWWebVersion());
    console.log("WWebJS v", require("whatsapp-web.js").version);
});
