AttributeError: '_SpecialForm' object has no attribute 'avro_schema_to_python'

Given a class such as this:

@dataclass
class BaseSchema(AvroModel):
    message_metadata: Dict[str, Any]

To Reproduce
calling
schema = BaseSchema.avro_schema()
produces the error
AttributeError: '_SpecialForm' object has no attribute 'avro_schema_to_python'

Expected behavior
It should return the schema

Thanks @aeldaly-tc. Any is not a valid type in avro, you must use a proper type as the documentation describe. Anyway, we should show a more user friendly message for this case.

Just a contribution, fields with datetime.timestamp type also throws the following exception:

AttributeError: 'method_descriptor' object has no attribute 'avro_schema_to_python'

Hi @leoscalco,

Do you mean that is not working for datetimes that are represented as timestamp? If that is the case, we do not have support for that. The logical types supported are: https://marcosschroh.github.io/dataclasses-avroschema/logical_types/

Maybe we can do something about it.

I realized this after commenting here.

I was using long type for timestamps, but I found in your document the right way to work with dates.

Now, any sink connector is recognizing my date. Anyway thank you for support.

Hi,

Perfect. I was thinking to add a new type to handle this option but maybe it not worth it at all. the user can make datetime.fromtimestamp(a_timestamp) and use the datetime.datetime type
