            >>> client = errorreporting_v1beta1.ReportErrorsServiceClient()

        Args:
            project_name (str): [Required] The resource name of the Google Cloud Platform project.
                Written as ``projects/`` plus the `Google Cloud Platform project
                ID <https://support.google.com/cloud/answer/6158840>`__. Example:
                ``projects/my-project-123``.
            event (Union[dict, ~google.cloud.errorreporting_v1beta1.types.ReportedErrorEvent]): [Required] The error event to be reported.

                If a dict is provided, it must be of the same form as the protobuf
                message :class:`~google.cloud.errorreporting_v1beta1.types.ReportedErrorEvent`
            retry (Optional[google.api_core.retry.Retry]):  A retry object used
                to retry requests. If ``None`` is specified, requests will not
                be retried.
            timeout (Optional[float]): 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.
            metadata (Optional[Sequence[Tuple[str, str]]]): Additional metadata
                that is provided to the method.

        Returns:
            A :class:`~google.cloud.errorreporting_v1beta1.types.ReportErrorEventResponse` instance.

        Raises:
            google.api_core.exceptions.GoogleAPICallError: If the request
                    failed for any reason.
            google.api_core.exceptions.RetryError: If the request failed due
                    to a retryable error and retry attempts failed.
            ValueError: If the parameters are invalid.
