Please read the pinned thread and format the code properly (and use the same formatting for the error message); and please try to explain a little bit about what you are trying to do and what you want to know.

You’re expecting that the request always returns JSON data, but, clearly, it doesn’t.

Try printing the value of request.text to see what it’s actually returning.
