- * The set of Firebase Functions status codes.
- *
- * The codes are the same at the ones exposed by [gRPC](https://github.com/grpc/grpc/blob/master/doc/statuscodes.md).
- *
- * Possible values:
- * - `cancelled`: The operation was cancelled (typically by the caller).
- * - `unknown`: Unknown error or an error from a different error domain.
- * - `invalid-argument`: 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. an invalid field name).
- * - `deadline-exceeded`: Deadline expired before 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.
- * - `not-found`: Some requested document was not found.
- * - `already-exists`: Some document that we attempted to create already
- *   exists.
- * - `permission-denied`: The caller does not have permission to execute the
- *   specified operation.
- * - `resource-exhausted`: Some resource has been exhausted, perhaps a
- *   per-user quota, or perhaps the entire file system is out of space.
- * - `failed-precondition`: Operation was rejected because the system is not
- *   in a state required for the operation's execution.
- * - `aborted`: The operation was aborted, typically due to a concurrency
- *   issue like transaction aborts, etc.
- * - `out-of-range`: Operation was attempted past the valid range.
- * - `unimplemented`: Operation is not implemented or not supported/enabled.
- * - `internal`: Internal errors. Means some invariants expected by
- *   underlying system has been broken. If you see one of these errors,
- *   something is very broken.
- * - `unavailable`: The service is currently unavailable. This is most likely
- *   a transient condition and may be corrected by retrying with a backoff.
- * - `data-loss`: Unrecoverable data loss or corruption.
- * - `unauthenticated`: The request does not have valid authentication
- *   credentials for the operation.
