class CloudVisionProductCreateOperator(BaseOperator):
    """
    Creates and returns a new product resource.

    Possible errors regarding the `Product` object provided:

    - Returns INVALID_ARGUMENT if `display_name` is missing or longer than 4096 characters.
    - Returns INVALID_ARGUMENT if `description` is longer than 4096 characters.
    - Returns INVALID_ARGUMENT if `product_category` is missing or invalid.

    .. seealso::
        For more information on how to use this operator, take a look at the guide:
        :ref:`howto/operator:CloudVisionProductCreateOperator`

    :param location: (Required) The region where the Product should be created. Valid regions
        (as of 2019-02-05) are: us-east1, us-west1, europe-west1, asia-east1
    :type location: str
    :param product: (Required) The product to create. If a dict is provided, it must be of the same form as
        the protobuf message `Product`.
    :type product: dict or google.cloud.vision_v1.types.Product
    :param project_id: (Optional) The project in which the Product should be created. If set to None or
        missing, the default project_id from the GCP connection is used.
    :type project_id: str
    :param product_id: (Optional) A user-supplied resource id for this Product.
        If set, the server will attempt to use this value as the resource id. If it is
        already in use, an error is returned with code ALREADY_EXISTS. Must be at most
        128 characters long. It cannot contain the character /.
    :type product_id: str
    :param retry: (Optional) A retry object used to retry requests. If `None` is
        specified, requests will not be retried.
    :type retry: google.api_core.retry.Retry
    :param timeout: (Optional) The amount of time, in seconds, to wait for the request to
        complete. Note that if retry is specified, the timeout applies to each individual
        attempt.
    :type timeout: float
    :param metadata: (Optional) Additional metadata that is provided to the method.
    :type metadata: Sequence[Tuple[str, str]]
    :param gcp_conn_id: The connection ID used to connect to Google Cloud Platform.
