-        # The `Status` message contains three pieces of data: error code, error message,
-        # and error details. The error code should be an enum value of
-        # google.rpc.Code, but it may accept additional error codes if needed.  The
-        # error message should be a developer-facing English message that helps
-        # developers *understand* and *resolve* the error. If a localized user-facing
-        # error message is needed, put the localized message in the error details or
-        # localize it in the client. The optional error details may contain arbitrary
-        # information about the error. There is a predefined set of error detail types
-        # in the package `google.rpc` that can be used for common error conditions.
-        #

-        # The `Status` message is the logical representation of the error model, but it
-        # is not necessarily the actual wire format. When the `Status` message is
-        # exposed in different client libraries and different wire protocols, it can be
-        # mapped differently. For example, it will likely be mapped to some exceptions
-        # in Java, but more likely mapped to some error codes in C.

-        # environments, either with or without APIs, to provide a
-        # consistent developer experience across different environments.
-        #
-        # Example uses of this error model include:
-        #
-        # - Partial errors. If a service needs to return partial errors to the client,
-        #     it may embed the `Status` in the normal response to indicate the partial
-        #     errors.
-        #
-        # - Workflow errors. A typical workflow has multiple steps. Each step may
-        #     have a `Status` message for error reporting.
-        #
-        # - Batch operations. If a client uses batch request and batch response, the
-        #     `Status` message should be used directly inside batch response, one for
-        #     each error sub-response.
-        #
-        # - Asynchronous operations. If an API call embeds asynchronous operation
-        #     results in its response, the status of those operations should be
-        #     represented directly using the `Status` message.
-        #

-        #     be used directly after any stripping needed for security/privacy reasons.
