Pulp

After updating from pulpcore 3.9 to 3.11 I can no longer browse the list of repositories in Pulp. Trying to access '/pulp/content/' results in a 500 error with following error from pulpcore-content service:

[2021-04-07 06:14:26 +0000] [2135216] [ERROR] Error handling request

    directory_list = ["{}/".format(d.base_path) for d in base_paths]
AttributeError: 'str' object has no attribute 'base_path'

Access to the repository publications/distributions are working fine, so this is more of a cosmetic problem for me, also I have built some tooling and monitoring relying on being able to list and browse repos via web browser.

Is this an expected behaviour? I couldn't find anything in the release notes but I might be missing something.

Using:

python3-pulp-rpm-3.9.1-1.el8.noarch
python3-pulpcore-3.11.0-1.el8.noarch
