View/edit binary Protocol Buffers messages

Describes violations in a client request. This error type focuses on the syntactic aspects of the request.

• repeated BadRequest.FieldViolation field_violations = 1

  Describes all violations in a client request.

A message type used to describe a single bad request field.

Used in: BadRequest

• string field = 1

  A path that leads to a field in the request body. The value will be a sequence of dot-separated identifiers that identify a protocol buffer field. Consider the following: ```text,json message CreateContactRequest { message EmailAddress { enum Type { TYPE_UNSPECIFIED = 0; HOME = 1; WORK = 2; } optional string email = 1; repeated EmailType type = 2; } string full_name = 1; repeated EmailAddress email_addresses = 2; } ``` In this example, in proto `field` could take one of the following values: * `full_name` for a violation in the `full_name` value * `email_addresses[1].email` for a violation in the `email` field of the first `email_addresses` message * `email_addresses[3].type[2]` for a violation in the second `type` value in the third `email_addresses` message. In JSON, the same values are represented as: * `fullName` for a violation in the `fullName` value * `emailAddresses[1].email` for a violation in the `email` field of the first `emailAddresses` message * `emailAddresses[3].type[2]` for a violation in the second `type` value in the third `emailAddresses` message.

• string description = 2

  A description of why the request element is bad.

• string reason = 3

  The reason of the field-level error. This is a constant value that identifies the proximate cause of the field-level error. It should uniquely identify the type of the FieldViolation within the scope of the google.rpc.ErrorInfo.domain. This should be at most 63 characters and match a regular expression of `[A-Z][A-Z0-9_]+[A-Z0-9]`, which represents UPPER_SNAKE_CASE.

• optional LocalizedMessage localized_message = 4

  Provides a localized error message for field-level errors that is safe to return to the API consumer.

Describes additional debugging info.

• repeated string stack_entries = 1

  The stack trace entries indicating where the error occurred.

• string detail = 2

  Additional debugging information provided by the server.

Describes the cause of the error with structured details. Example of an error when contacting the "pubsub.googleapis.com" API when it is not enabled: ```text,json { "reason": "API_DISABLED" "domain": "googleapis.com" "metadata": { "resource": "projects/123", "service": "pubsub.googleapis.com" } } ``` This response indicates that the pubsub.googleapis.com API is not enabled. Example of an error that is returned when attempting to create a Spanner instance in a region that is out of stock: ```text,json { "reason": "STOCKOUT" "domain": "spanner.googleapis.com", "metadata": { "availableRegions": "us-central1,us-east2" } } ```

• string reason = 1

  The reason of the error. This is a constant value that identifies the proximate cause of the error. Error reasons are unique within a particular domain of errors. This should be at most 63 characters and match a regular expression of `[A-Z][A-Z0-9_]+[A-Z0-9]`, which represents UPPER_SNAKE_CASE.

• string domain = 2

  The logical grouping to which the "reason" belongs. The error domain is typically the registered service name of the tool or product that generates the error. Example: "pubsub.googleapis.com". If the error is generated by some common infrastructure, the error domain must be a globally unique value that identifies the infrastructure. For Google API infrastructure, the error domain is "googleapis.com".

• map<string, string> metadata = 3

  Additional structured details about this error. Keys must match a regular expression of `[a-z][a-zA-Z0-9-_]+` but should ideally be lowerCamelCase. Also, they must be limited to 64 characters in length. When identifying the current value of an exceeded limit, the units should be contained in the key, not the value. For example, rather than `{"instanceLimit": "100/request"}`, should be returned as, `{"instanceLimitPerRequest": "100"}`, if the client exceeds the number of instances that can be created in a single (batch) request.

Provides links to documentation or for performing an out of band action. For example, if a quota check failed with an error indicating the calling project hasn't enabled the accessed service, this can contain a URL pointing directly to the right place in the developer console to flip the bit.

• repeated Help.Link links = 1

  URL(s) pointing to additional information on handling the current error.

Describes a URL link.

Used in: Help

• string description = 1

  Describes what the link offers.

• string url = 2

  The URL of the link.

Provides a localized error message that is safe to return to the user which can be attached to an RPC error.

Used in: BadRequest.FieldViolation

• string locale = 1

  The locale used following the specification defined at https://www.rfc-editor.org/rfc/bcp/bcp47.txt. Examples are: "en-US", "fr-CH", "es-MX"

• string message = 2

  The localized error message in the above locale.

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.

• repeated PreconditionFailure.Violation violations = 1

  Describes all precondition violations.

A message type used to describe a single precondition failure.

Used in: PreconditionFailure

• string type = 1

  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".

• string subject = 2

  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.

• string description = 3

  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".

Describes how a quota check failed. For example if a daily limit was exceeded for the calling project, a service could respond with a QuotaFailure detail containing the project id and the description of the quota limit that was exceeded. If the calling project hasn't enabled the service in the developer console, then a service could respond with the project id and set `service_disabled` to true. Also see RetryInfo and Help types for other details about handling a quota failure.

• repeated QuotaFailure.Violation violations = 1

  Describes all quota violations.

A message type used to describe a single quota violation. For example, a daily quota or a custom quota that was exceeded.

Used in: QuotaFailure

• string subject = 1

  The subject on which the quota check failed. For example, `clientip:<ip address of client>` or `project:<Google developer project id>`.

• string description = 2

  A description of how the quota check failed. Clients can use this description to find more about the quota configuration in the service's public documentation, or find the relevant quota limit to adjust through developer console. For example: "Service disabled" or "Daily Limit for read operations exceeded".

Contains metadata about the request that clients can attach when filing a bug or providing other forms of feedback.

• string request_id = 1

  An opaque string that should only be interpreted by the service generating it. For example, it can be used to identify requests in the service's logs.

• string serving_data = 2

  Any data that was used to serve this request. For example, an encrypted stack trace that can be sent back to the service provider for debugging.

Describes the resource that is being accessed.

• string resource_type = 1

  A name for the type of resource being accessed, e.g. "sql table", "cloud storage bucket", "file", "Google calendar"; or the type URL of the resource: e.g. "type.googleapis.com/google.pubsub.v1.Topic".

• string resource_name = 2

  The name of the resource being accessed. For example, a shared calendar name: "example.com_4fghdhgsrgh@group.calendar.google.com", if the current error is [google.rpc.Code.PERMISSION_DENIED][google.rpc.Code.PERMISSION_DENIED].

• string owner = 3

  The owner of the resource (optional). For example, `user:<owner email>` or `project:<Google developer project id>`.

• string description = 4

  Describes what error is encountered when accessing this resource. For example, updating a cloud project may require the `writer` permission on the developer console project.

Describes when the clients can retry a failed request. Clients could ignore the recommendation here or retry when this information is missing from error responses. It's always recommended that clients should use exponential backoff when retrying. Clients should wait until `retry_delay` amount of time has passed since receiving the error response before retrying. If retrying requests also fail, clients should use an exponential backoff scheme to gradually increase the delay between retries based on `retry_delay`, until either a maximum number of retries have been reached or a maximum retry delay cap has been reached.

• optional protobuf.Duration retry_delay = 1

  Clients should wait at least this long between retrying the same request.

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). 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](https://cloud.google.com/apis/design/errors).

• int32 code = 1

  The status code, which should be an enum value of [google.rpc.Code][google.rpc.Code].

• string message = 2

  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][google.rpc.Status.details] field, or localized by the client.

• repeated protobuf.Any details = 3

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