This is possibly an error in your code, it could be in the Puppeteer configuration.

You can call the functions directly through the browser console and test them.
In a simple way: open the project through VSCode -> Run -> Start Debugging, it will open an instance of chrome, you can directly call the function in the console.

Something like:

await WPP.chat.getMessageById('messageId');

You can see that it continues to function normally.

Well, did you do that and did it work? We have to check your code, but there is a problem in Puppeteer, an issue already known and discussed by them, which brings undefined returns, in the WppConnect LIB it is treated like this: JSON.parse(JSON.stringify(result));

It's something you can try, here's a reference:
