2. Create Circuits and assign them to the location
3. Try to filter the Circuits list with the location

Expected Behavior

A list of circuits assigned to this location

Unsupported lookup 'slug' for AutoSlugField or join on the field not permitted.

Python version: 3.9.2

Thanks for the report! Confirmed reproducible on demo.nautobot.com.

Interestingly appears to not be an issue in next as far as I can tell.

As a guess the issue may be here:

https://github.com/nautobot/nautobot/blob/develop/nautobot/circuits/filters.py#L157

terminations__location__slug should probably be just terminations__location.

It also looks like we're missing coverage for this filter in nautobot/circuits/tests/test_filters.py in 1.5.x - this issue was fixed and test coverage was added in next by #3131.

Is there a release date for next?
