Hello there,

This is not the first time I have come across this bug, it has been there since broadcastMessage was created.

Back then I didn't know how to solve it, and I'm guessing I still don't know. If by any chance you have an idea or clue on how to solve it, I would love the input.

Anyway, my best recommendation right now is setting "skipLibCheck": true inside your tsconfig.json, as the error only appears when type-checking the compiled library and it still works with full type support.

That's the annoying thing, it doesn't throw an error while building, only in prod.

I will try to mess with it later today, thanks for raising this issue!

Yes that's exacly what i did, thank you! I think it should be something like typeof WhatsAppAPI['sendMessage'] instead of typeof this.sendMessage

Oh, wow, I'm just really dumb. I don't know why I never did the obvious thing 🤣.

I will try to do a release in a few hours, thanks for the help!
