Not an error; returned on success.

HTTP Mapping: 200 OK

The operation was cancelled, typically by the caller.

HTTP Mapping: 499 Client Closed Request

Unknown error. For example, this error may be returned when aStatus value received from another address space belongs to an error space that is not known in this address space. Also errors raised by APIs that do not return enough error information may be converted to this error.

HTTP Mapping: 500 Internal Server Error

The client specified an invalid argument. Note that this differs fromFAILED_PRECONDITION.INVALID_ARGUMENT indicates arguments that are problematic regardless of the state of the system (e.g., a malformed file name).

HTTP Mapping: 400 Bad Request

The deadline expired before the operation could complete. For operations that change the state of the system, this error may be returned even if the operation has completed successfully. For example, a successful response from a server could have been delayed long enough for the deadline to expire.

HTTP Mapping: 504 Gateway Timeout

Some requested entity (e.g., file or directory) was not found.

Note to server developers: if a request is denied for an entire class of users, such as gradual feature rollout or undocumented allowlist,NOT_FOUND may be used. If a request is denied for some users within a class of users, such as user-based access control,PERMISSION_DENIED must be used.

HTTP Mapping: 404 Not Found

The entity that a client attempted to create (e.g., file or directory) already exists.

HTTP Mapping: 409 Conflict

The caller does not have permission to execute the specified operation.PERMISSION_DENIED must not be used for rejections caused by exhausting some resource (useRESOURCE_EXHAUSTED instead for those errors).PERMISSION_DENIED must not be used if the caller can not be identified (useUNAUTHENTICATED instead for those errors). This error code does not imply the request is valid or the requested entity exists or satisfies other pre-conditions.

HTTP Mapping: 403 Forbidden

The request does not have valid authentication credentials for the operation.

HTTP Mapping: 401 Unauthorized

Some resource has been exhausted, perhaps a per-user quota, or perhaps the entire file system is out of space.

HTTP Mapping: 429 Too Many Requests

The operation was rejected because the system is not in a state required for the operation's execution. For example, the directory to be deleted is non-empty, an rmdir operation is applied to a non-directory, etc.

Service implementors can use the following guidelines to decide betweenFAILED_PRECONDITION,ABORTED, andUNAVAILABLE: (a) UseUNAVAILABLE if the client can retry just the failing call. (b) UseABORTED if the client should retry at a higher level. For example, when a client-specified test-and-set fails, indicating the client should restart a read-modify-write sequence. (c) UseFAILED_PRECONDITION if the client should not retry until the system state has been explicitly fixed. For example, if an "rmdir" fails because the directory is non-empty,FAILED_PRECONDITION should be returned since the client should not retry unless the files are deleted from the directory.

HTTP Mapping: 400 Bad Request

The operation was aborted, typically due to a concurrency issue such as a sequencer check failure or transaction abort.

See the guidelines above for deciding betweenFAILED_PRECONDITION,ABORTED, andUNAVAILABLE.

HTTP Mapping: 409 Conflict

The operation was attempted past the valid range. E.g., seeking or reading past end-of-file.

UnlikeINVALID_ARGUMENT, this error indicates a problem that may be fixed if the system state changes. For example, a 32-bit file system will generateINVALID_ARGUMENT if asked to read at an offset that is not in the range [0,2^32-1], but it will generateOUT_OF_RANGE if asked to read from an offset past the current file size.

There is a fair bit of overlap betweenFAILED_PRECONDITION andOUT_OF_RANGE. We recommend usingOUT_OF_RANGE (the more specific error) when it applies so that callers who are iterating through a space can easily look for anOUT_OF_RANGE error to detect when they are done.

HTTP Mapping: 400 Bad Request

The operation is not implemented or is not supported/enabled in this service.

HTTP Mapping: 501 Not Implemented

Internal errors. This means that some invariants expected by the underlying system have been broken. This error code is reserved for serious errors.

HTTP Mapping: 500 Internal Server Error

The service is currently unavailable. This is most likely a transient condition, which can be corrected by retrying with a backoff. Note that it is not always safe to retry non-idempotent operations.

See the guidelines above for deciding betweenFAILED_PRECONDITION,ABORTED, andUNAVAILABLE.

HTTP Mapping: 503 Service Unavailable

Unrecoverable data loss or corruption.

HTTP Mapping: 500 Internal Server Error

int32

The status code, which should be an enum value ofgoogle.rpc.Code.

string

A developer-facing error message, which should be in English. Any user-facing error message should be localized and sent in thegoogle.rpc.Status.details field, or localized by the client.

Any

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