+        # different programming environments, including REST APIs and RPC APIs. It is
+        # used by [gRPC](https://github.com/grpc). The error model is designed to be:
+        #
+        # - Simple to use and understand for most users
+        # - Flexible enough to meet unexpected needs
+        #
+        # # Overview
+        #
+        # 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.
+        #
+        # # Language mapping
+        #
+        # 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.
+        #
+        # # Other uses
+        #
+        # The error model and the `Status` message can be used in a variety of
+        # 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.
+        #
+        # - Logging. If some API errors are stored in logs, the message `Status` could
+        #     be used directly after any stripping needed for security/privacy reasons.
+      "message": "A String", # A developer-facing error message, which should be in English. Any
+          # user-facing error message should be localized and sent in the
+          # google.rpc.Status.details field, or localized by the client.

+        # `Get`/`Create`/`Update`, the response should be the resource.  For other

+    "metadata": { # Service-specific metadata associated with the operation.  It typically
+        # contains progress information and common metadata such as create time.

+        #
+        # 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.
+        #
+        # # Language mapping
+        #
+        # 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.
+        #
+        # # Other uses
+        #
+        # The error model and the `Status` message can be used in a variety of
+        # environments, either with or without APIs, to provide a

+        #
+        # Example uses of this error model include:

+        #
+        # - 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

+        #
