While running :

/ail-framework/bin/crawlers/Crawler.py

Does this error related to lacus ?

Traceback (most recent call last):
  File "/root/ail-framework/AILENV/lib/python3.8/site-packages/redis/connection.py", line 78, in pack
    output.append(hiredis.pack_command(args))
TypeError: A tuple item must be str, int, float or bytes.

During handling of the above exception, another exception occurred:

That's a weird issue, generally means that one of the value added to redis is None, but that doesn't makes much sense there on the call r_cache.hset(f'crawler:capture:{self.uuid}', 'status', CaptureStatus.UNKNOWN).

Having a quick look at the code makes me think that you're either using an old version of the project, or that the script was still running on that old version of the code when it crashed.

@Terrtia any idea?
