Field required error when

[nuest]

I'm creating a new Metadata object using the example from the README and get an error, which surprises me because it should not happen according to your tests:

Creator(
            name="Hoyt, Charles Tapley",
            affiliation="Harvard Medical School",
            orcid="0000-0003-4423-4370",
        )

[cthoyt]

this smells like a pydantic 1/2 issue

[nuest]

A fix is to set gnd=None by the way.

[cthoyt]

I think at #20 solves this, but I need to read the issues with CI (probably stuff unrelated due to e.g., updates in sphinx)

[cthoyt]

20 seems to be passing tests on pydantic 1/2, please let me know if this fixes this issue
