Problem with Enums

[renaisser]

Hi team!

I have the following problem. I have the next code:

class ClassDoc(str, Enum):
    NDA = "nda"
    SERVICE_AGREEMENT = "service_agreement"
    JUDICIAL_SENTENCE = "judicial_sentence"
    LABOR = "labor"
    LEGAl_LETTER = "legal_letter"
    INVOICE = "invoice"
    OFFICIAL_JOURNAL = "official_journal"
    OTHER = "other"
    LAWSUIT = "lawsuit"
    COMPLAINT = "complaint"
    CLAIM = "claim" 

When I run my code locally, everything is okay, but when I run the same code in Google Cloud Run, I get this error:

Uncaught Exception: 2 validation errors for RenMetadata

  Input should be an instance of Langs [type=is_instance_of, input_value='es', input_type=str]

  Input should be an instance of ClassDoc [type=is_instance_of, input_value='service_agreement', input_type=str]
    For further information visit https://errors.pydantic.dev/2.7/v/is_instance_of

I don't understand why... any idea?

Thanks a lot in advance.
