[BUG] Prospector fails pylint error - 1.13.x

[robertalexa]

Hi,

Upgrading from 1.12.1 to any of the 1.13.x versions ends with with a pylint error on Django.

Python version used - 3.13

Unfortunately I understand too little about the chain from propesctor to pylint and how astroid intervenes, so I won't even pretend to make an assumption on this one.

Happy to do further testing if required. Here is a traceback of the error.

PS: @Pierre-Sassoulas I know you have helped tremendously migrating to the new python version and you have helped work through the snags of this. Any chance you can assist with this?

Thanks in advance
