RecursionError: maximum recursion depth exceeded in __instancecheck__ about protobuf_to_pydantic HOT 3 CLOSED

Thank you for your feedback, based on the error message it was inferred to be a Message loop reference issue, I have now pushed the fix code to branch 7-recursionerror-maximum-recursion-depth-exceeded-in-__instancecheck__. You can clone it locally to verify that the problem is fixed, and if not, please provide a Protobuf file that minimally reproduces the problem @pppwaw

from protobuf_to_pydantic.

syntax = "proto3";

message InvoiceItem {
  string name = 1;
  int32 amount = 2; 
  int32 quantity = 3;
  repeated InvoiceItem items = 4;
}

It can reproduces the problem.
In pydantic, it can can be solve by This page

Also:

1. the 15 line in code_gen.py , it's if __version__ < "4.0.0":, it should be if __version__ > "4.0.0":
2. Should we add a pass to a message that does not contain any fields?

Thank you for the Protobuf file, I will fix this over the weekend and add enough tests to cover the different versions of the Protobuf pkg
