JSONDecodeError for Google Search Console API sample script in Python

I am trying to query my Google Search Console Data with the Search Console API. The script is here..

I am using OS and python3. I have the client_secret.py file in the same directory which I am 85% sure I authorized.

When I run it on a different computer, it works fine. I am sorry this explanation is not going to be great. I simply have no idea why the script doesn't work for me, but its working fine for my colleague. I suspect it has something to do with the haphazardness of my user/bin files. Anyway, if you can check out my query and error codes, maybe theres something more obvious. (I'm new).

This is my query. I've tried it in 129487321904 different variations:

$ python3 search_analytics_api_sample.py 'https://www.uselessthingstobuy.com/' '2020-02-10' '2020-03-10'

This are my errors:

I cannot for the life of me figure this one out. I tried installing all the necessary packages in a virtual environment, and I'm getting the same error.

I also have miniconda for no apparent reason. Could this be conflicting with anaconda in this case? I really have no idea what I'm doing, but I need to get this API to work for me. I haven't found anything in the crazy Google Developers documents, which are sooo confusing. And, I haven't found anyone with the same jsonDecoder error for this script. Thanks!

• edit: I removed miniconda, still getting the same error
