The canonical error codes for gRPC APIs.
Sometimes multiple error codes may apply. Services should return the most specific error code that applies. For example, prefer OUT_OF_RANGE over FAILED_PRECONDITION if both codes apply. Similarly prefer NOT_FOUND or ALREADY_EXISTS over FAILED_PRECONDITION.
Protobuf type google.rpc.Code
| Constants |
| public Google 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 Generated from protobuf enum ABORTED = 10; |
| public Google 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; |
| public Google The operation was cancelled, typically by the caller. HTTP Mapping: 499 Client Closed Request Generated from protobuf enum CANCELLED = 1; |
| public Google Unrecoverable data loss or corruption. HTTP Mapping: 500 Internal Server Error Generated from protobuf enum DATA_LOSS = 15; |
| public Google 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; |
| public Google 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 Generated from protobuf enum FAILED_PRECONDITION = 9; |
| public Google 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; |
| public Google The client specified an invalid argument. Note that this differs from HTTP Mapping: 400 Bad Request Generated from protobuf enum INVALID_ARGUMENT = 3; |
| public Google 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, Generated from protobuf enum NOT_FOUND = 5; |
| public Google Not an error; returned on success. HTTP Mapping: 200 OK Generated from protobuf enum OK = 0; |
| public Google The operation was attempted past the valid range. E.g., seeking or reading past end-of-file. Unlike Generated from protobuf enum OUT_OF_RANGE = 11; |
| public Google The caller does not have permission to execute the specified operation. HTTP Mapping: 403 Forbidden Generated from protobuf enum PERMISSION_DENIED = 7; |
| public Google 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; |
| public Google The request does not have valid authentication credentials for the operation. HTTP Mapping: 401 Unauthorized Generated from protobuf enum UNAUTHENTICATED = 16; |
| public Google 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 between Generated from protobuf enum UNAVAILABLE = 14; |
| public Google The operation is not implemented or is not supported/enabled in this service. HTTP Mapping: 501 Not Implemented Generated from protobuf enum UNIMPLEMENTED = 12; |
| public Google Unknown error. For example, this error may be returned when a HTTP Mapping: 500 Internal Server Error Generated from protobuf enum UNKNOWN = 2; |
