I think the issue is you have the second argument ("grant_type=client_
credentials") as the data for the post, and then the "json=..." argument
also as data for the post.
The API for post() is that it either takes the data as the second argument
to the function, or as a keyword argument "data" or a keyword argument
"json" . It has to be only one of those options.
