[Python] How to solve mypy error for @property with pydantic @computed_field?

I need to decorate @property with the @computed_field from pydantic (to automatically generate key-value pairs and include them in a FastAPI JSON Response). In the following example, mypy displays an error. If there is an error, how can I fix it? If everything is correct, how do I disable this mypy message?

from pydantic import BaseModel, computed_field

class MyClass(BaseModel):

value1: str
value2: str

@computed_field
@property
def joined_values(self) -> str:
return self.value1 + self.value2


obj = MyClass(value1="1", value2="2")
print(f"{obj.joined_values=}") # obj.joined_values='12'


mypy error:

$ mypy .
stackperflow_pydantic_property.py:25: error: Decorators on top of @property are not supported [misc]
