Getting this python SDK Error. Any ideas? "ClassValidationError: While structuring CatalogDeclarativeUsersUserGroups (1 sub-exception)"

Hello, What Python SDK version do you use?

Hi Doug, I've tested this call on your sandbox and it returned a properly formatted list of seven users (including yours). Can you please confirm the SDK version you're using? If it is indeed v1.37.0, can you DM me a short reproducer code for this error, please?
