Pydantic unable to generate schema when importing weaviate

[Josipmrden]

How to reproduce this bug?

It happens during the loading the module for Memgraph. In the local environment, I'm able to add the module and do the code with it, which is a bit weird

[Please let me know if I need to submit this issue to some other repository]

What is the expected behavior?

Should work well with Pydantic

What is the actual behavior?

hi @Josipmrden !!

Can you give us some more context? It could really help to provide a way we could reproduce this.

THanks!
