I solve this error in the console by updating whatsapp-web.js, I recommend you try both options 1 - run npm update whatsapp-web.js 2 - Delete the folder node_modules and reinstall.

It didn't work either way...

Try to uninstall and install the package:

npm uninstall whatsapp-web.js
npm install whatsapp-web.js

I believe the issue here is that the install link from the first reference in "whatsapp-web" Google search points to [email protected]. Make sure to take a look at the latest versions.

For me, the bug was in calling the processAttachments method. Changed the order of the parameters.

Credits to https://github.com/vilsonei, that fix the bug.

Working here:

  var mc = new Store.MediaCollection(chat);
  mc.processAttachments([{ file: mediaBlob }, 1], 1, chat).then(() => {
    var media = mc._models[0]
    media.sendToChat(chat, { caption: caption });
  });

I have the same issue... on latest 1.24.0
