Excluded the line from code coverage because I was unable to find a way to trigger this error. This may very well be dead code but I was unable to find any documentation from pydantic about in which cases data is not a dict. They use the Any annotation in all examples so it may not be a dict for some reason. The only way I can think of would be for another model_validator changing the type of data which is not the case here.
