Not an error; returned on success HTTP Mapping: 200 OK

Generated from protobuf enum OK = 0;

The operation was cancelled, typically by the caller.

HTTP Mapping: 499 Client Closed Request

Generated from protobuf enum CANCELLED = 1;

Unknown error. For example, this error may be returned when a Status 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

Generated from protobuf enum UNKNOWN = 2;

The client specified an invalid argument. Note that this differs from FAILED_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

Generated from protobuf enum INVALID_ARGUMENT = 3;

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

Generated from protobuf enum DEADLINE_EXCEEDED = 4;

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

For privacy reasons, this code may be returned when the client does not have the access rights to the entity, though such usage is discouraged. HTTP Mapping: 404 Not Found

Generated from protobuf enum NOT_FOUND = 5;

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

HTTP Mapping: 409 Conflict

Generated from protobuf enum ALREADY_EXISTS = 6;

The caller does not have permission to execute the specified operation. PERMISSION_DENIED must not be used for rejections caused by exhausting some resource (use RESOURCE_EXHAUSTED instead for those errors). PERMISSION_DENIED must not be used if the caller can not be identified (use UNAUTHENTICATED instead for those errors).

HTTP Mapping: 403 Forbidden

Generated from protobuf enum PERMISSION_DENIED = 7;

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

HTTP Mapping: 401 Unauthorized

Generated from protobuf enum UNAUTHENTICATED = 16;

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

Generated from protobuf enum RESOURCE_EXHAUSTED = 8;

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 between FAILED_PRECONDITION, ABORTED, and UNAVAILABLE: (a) Use UNAVAILABLE if the client can retry just the failing call. (b) Use ABORTED if the client should retry at a higher level (e.g., restarting a read-modify-write sequence). (c) Use FAILED_PRECONDITION if the client should not retry until the system state has been explicitly fixed. E.g., 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

Generated from protobuf enum FAILED_PRECONDITION = 9;

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 between FAILED_PRECONDITION, ABORTED, and UNAVAILABLE. HTTP Mapping: 409 Conflict

Generated from protobuf enum ABORTED = 10;

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

Unlike INVALID_ARGUMENT, this error indicates a problem that may be fixed if the system state changes. For example, a 32-bit file system will generate INVALID_ARGUMENT if asked to read at an offset that is not in the range [0,2^32-1], but it will generate OUT_OF_RANGE if asked to read from an offset past the current file size. There is a fair bit of overlap between FAILED_PRECONDITION and OUT_OF_RANGE. We recommend using OUT_OF_RANGE (the more specific error) when it applies so that callers who are iterating through a space can easily look for an OUT_OF_RANGE error to detect when they are done. HTTP Mapping: 400 Bad Request

Generated from protobuf enum OUT_OF_RANGE = 11;

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

HTTP Mapping: 501 Not Implemented

Generated from protobuf enum UNIMPLEMENTED = 12;

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

Generated from protobuf enum INTERNAL = 13;

The service is currently unavailable. This is most likely a transient condition, which can be corrected by retrying with a backoff.

See the guidelines above for deciding between FAILED_PRECONDITION, ABORTED, and UNAVAILABLE. HTTP Mapping: 503 Service Unavailable

Generated from protobuf enum UNAVAILABLE = 14;

Unrecoverable data loss or corruption.

HTTP Mapping: 500 Internal Server Error

Generated from protobuf enum DATA_LOSS = 15;
