        # The Status type defines a logical error model that is suitable for different

        # (https://github.com/grpc). The error model is designed to be:
        # Simple to use and understand for most users
        # Flexible enough to meet unexpected needsOverviewThe 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 mappingThe 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 usesThe 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.

      # The Status type defines a logical error model that is suitable for 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 needsOverviewThe 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 mappingThe 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 usesThe 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.
