To Reproduce Steps to reproduce the behavior:

That’s good news. I’m happy to resolve your problem.

I don’t close this issue now. If I get the time then I will check the problem deeply.

@koxudaxi Hello, I just tried to reproduce and found that the import statement was import pydantic.generics instead of import pydantic. I think because the other place in the same file was using pydantic.generics.Generic.

I also found that it isn’t practical to import like that and using pydantic.validator later. Changing the import statement back to import pydantic works. I’m not sure if there is anything to fix in this case. Thanks!
