Response cannot be a simple type like int

[cropr]

Environment:

• Python version: 3.10
• Operating system: tested it on Windows 10 and Ubuntu 22.04
• Flask version: 2.0.3
• flask-openapi3 version: 2.0.0

I cannot create an endpoint that is returning an int (or any other native type)

@app.get("/path", responses={"200": int})
def apicall():
    return 1

gives error TypeError: <class 'int'> is invalid pydantic.BaseModel.

I could leave the responses out, but this makes the generated doc incomplete

Try to do something like this

class ResponseWithInt(BaseModel):
    __root__: int

That does indeed solve my question
