ValueError: invalid literal for int() with base 16: b''

I’m seeing this again while running twarc stream and am confused why twarc isn’t catching/restarting:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/urllib3/response.py", line 685, in _update_chunk_length
    self.chunk_left = int(line, 16)
ValueError: invalid literal for int() with base 16: b''

During handling of the above exception, another exception occurred:

I think this is fixed now - https://twittercommunity.com/t/filtered-stream-request-breaks-in-5-min-intervals/153926/20?u=igorbrigadir on twitter’s end. Unfortunately if there’s still doubt about our own error handling, it may not be possible to reproduce, unless we mock a connection and manually insert some bogus b'' data or something like that.

I think the twarc.decorators2.catch_requests_exceptions isn’t working with twarc.Twarc2.stream because even though the call to Twarc2.stream() is getting wrapped, it returns a response which is then streamed from with response.iter_lines(). It is during this iteration using iter_lines() that we need additional exception handling.
