def _serialize_data(self, data, serializer_class=None):

        Function to serialize data with the serializer given in the
        serializer_class attribute. Also validates the data and responds with
        a HTTP_400_BAD_REQUEST when validation failed. Due to being an open
        api we do not want to give away the required fields and their
        requirements.

        Args:
            data(dict): Dictonary with that data that need to be serialized.
            serializer_class(Serializer): Class to use for serialization.

        Returns:
            dict: Dictionary with the validated data.

        Raises:
            NotImplementedError: When serializer_class attribute is not set.
            ParseError: When validation fails but because it's an open API we
                do not want to give away what failed. ParseError returns a
                HTTP_400_BAD_REQUEST.
