vapi std errors: service unavailable

The service_unavailable error indicates that the service is unavailable.

Examples:

  • Attempt to invoke a operation when the server is too busy.
  • Attempt to invoke a operation when the server is undergoing maintenance.
  • An operation fails to contact VMware Tools running inside the virtual machine.

Counterexamples:

  • A client provides an invalid service or operation identifier when invoking the operation using a dynamic interface (for example REST). The vapi.std.errors.operation_not_found error would be used instead.
  • A client invokes the operation from the service, but that service has not been installed. The vapi.std.errors.operation_not_found error would be used instead.

Attributes:

Name Type Description
Required
messages localizable_message[] Stack of one or more localizable messages for human error consumers.

The message at the top of the stack (first in the list) describes the error from the perspective of the operation the client invoked. Each subsequent message in the stack describes the "cause" of the prior message.

Optional
data object Data to facilitate clients responding to the operation reporting a standard error to indicating that it was unable to complete successfully.

Operations may provide data that clients can use when responding to errors. Since the data that clients need may be specific to the context of the operation reporting the error, different operations that report the same error may provide different data in the error. The documentation for each each operation will describe what, if any, data it provides for each error it reports. The vapi.std.errors.argument_locations, vapi.std.errors.file_locations, and vapi.std.errors.transient_indication structures are intended as possible values for this field. vapi.std.dynamic_ID may also be useful as a value for this field (although that is not its primary purpose). Some services may provide their own specific structures for use as the value of this field when reporting errors from their operations.

Optional. Some operations will not set this field when reporting errors.
