Description

Ticket moved to GitHub: "pulp/pulpcore/1998":https://github.com/pulp/pulpcore/issues/1998


While working with Different RPM content types, and listing them, I hit the below error.

In [24]: rpm_content_package_categories.list(limit='500', repository_version='/pulp/api/v3/repositories/rpm/rpm/954de407-6872-4e62-b3d8-6019d30809aa/versions/1/', fields='pulp_href')                                                                                                                                [11/15244]

ValueError: Invalid value for `id`, must not be `None`

This appears to be due to the fact that numerous content types have "mandatory" fields, and if specifying fields = 'xyz' when performing a list, and a mandatory field is not included, you get a stack trace akin to the above.

I think, if there are required/mandatory fields for specific content, then the fields provided to list should be appended to a pre-defined list of mandatory fields.

Examples of mandatory fields.

Not sure if this sort of issue is also applicable to other plugins.
