      # 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 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` which 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 purpose. - Batch operations. If a client
