`JSONDecodeError: Expecting value` after some while

[wrobelda]

I got a JSONDecodeError: Expecting value error followed by a crash after some 100+ iterations. I possibly got throttled, since I set up a relative short interval. Nonetheless, it would be nice if the tool:

1. console-printed the top n lines of the JSON it actually received
2. sent a regular notification about the error
3. maybe increased an interval gradually until it received a valid JSON again, instead of quitting cowardly

Traceback I got:

Traceback (most recent call last):

During handling of the above exception, another exception occurred:
