what is error handling best practice in Flask restAPI

@app.errorhandler(InputError)
def handle_input_error(e):
    return {"message": e["message"], "status": e["status"]}

class MyErrors(Exception):
    status_code: int
    
    def __init__(self, message):
        super(MyErrors, self).__init__(message)
        self.message = message
        
    def response(self):
        return {"message": self.message, "status": self.status_code}
    
class InputError(MyErrors):
    status_code = 222
    
class SomeOtherError(MyErrors):
    status_code = 123

@app.errorhandler(MyErrors)
def handle_errors(e):
    return e.response()
