Error when running calibredb from Cron - Login related I think

[MrRalphMan]

Hi All,

I've been using


So I've installed Calibre on a Rocky Linux box and wanted to have an Incoming directory on the server, so I can drop any new books there and have a CRON job run to pick them up.
This works, but only for a while and then I get an Server 500 error.

Searching this seems to show this is a authentication issue, but I have the correct username/password in the command.

When it does start failing, I log onto the web based GUI, on port 8080, and it starts working.

So although the username/password is in the command, it doesn't work until I actually log into the server.

Cron line:

*/5 * * * * calibredb add /home/incoming_books/ -r --with-library http://localhost:8080#calibre-library --username <username> --password <password> && rm -r /home/incoming_books/*

UserID/Password and Path have been redacted.

This is the output I get:

Traceback (most recent call last):
  File "runpy.py", line 194, in _run_module_as_main
  File "runpy.py", line 87, in _run_code

mechanize._response.httperror_seek_wrapper: HTTP Error 500: Internal Server Error

What am I doing wrong or is this not something I can easily do?

Look at th elogs of the server to see what the actual error is.
