Thanks, and you're right the field is optional.

One thing: I'd make it Optional[str] = Field(default=None, ...). On its own Optional[str] accepts an explicit null but still rejects the field being absent, and AWS tends to just drop these fields rather than send null in some cases. The default covers both. A test for the missing field would round it out, then happy to approve.

Thanks, updated 👍

I noticed that the ruff target version is behind so I bumped it. After the bump ruff reports 2 B905 errors and 1017 errors from ruff upgrade rules. I fixed the former and added temporary ignores for the latter, to avoid adding noise to the PR. The upgrade errors are automatically fixable, so I can easily fix them in a separate commit if you prefer.
