New API - Create clip API error "The 'user_id' parameter cannot be blank."

You have not included the response

What was the error in this case?

Suggests you got a non 200 code.

Is not a valid broadcaster ID, gonna assume you have scrambled this for no reason.

So I cannot check the status of the stream.

You can only create a clip of a Stream that is live

Omit the whole secret. Not partially, have edited your post
