500 Internal Server Error

[ka-m-be]

I use mastodon-archiver to fetch from a friendica server, so this might not be happening with Mastodon.
It worked very well for months, but now I get

Traceback (most recent call last):
  File "/Users/xxx/Library/Python/3.11/bin/mastodon-archive", line 8, in <module>

mastodon.errors.MastodonInternalServerError: ('Mastodon API returned error', 500, 'Internal Server Error', None)

This happens when updating an existing archive and also when starting fresh.
I know it's a server problem, but would be grateful for hints.
Could it be because of pagination size? Total number of posts? A faulty post or data in the API request?

The version is fresh from the repo.

I have no idea. If the server gives back a 500 Internal Server Error, I think I'd search the server for logs. Perhaps there's more to be found, there? If you get into a discussion with the Friendica developers, make sure to tell them that the tool you're using uses Mastodon.py. Perhaps somebody can write a tiny Python application that logs in and fetches some statuses from a Friendica, just to see whether whether it is reproducible? If so, that small application could be appended to the issue for Friendica devs to use.
