PreconditionFailure
Describes what preconditions have failed.
For example, if an RPC failed because it required the Terms of Service to be acknowledged, it could list the terms of service violation in the PreconditionFailure message.

Violation
A message type used to describe a single precondition failure.
Fields | |
---|---|
type |
The type of PreconditionFailure. We recommend using a service-specific enum type to define the supported precondition violation subjects. For example, "TOS" for "Terms of Service violation". |
subject |
The subject, relative to the type, that failed. For example, "google.com/cloud" relative to the "TOS" type would indicate which terms of service is being referenced. |
description |
A description of how the precondition failed. Developers can use this description to understand how to fix the failure. For example: "Terms of service not accepted". |
Status
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. Each Status
message contains three pieces of data: error code, error message, and error details.
You can find out more about this error model and how to work with it in the API Design Guide.

message |
A developer-facing error message, which should be in English. Any user-facing error message should be localized and sent in the |

A list of messages that carry the error details. There is a common set of message types for APIs to use. |
