gRPC 1 CANCELLED vs 16 UNAUTHENTICATED
Both gRPC 1 (CANCELLED) and 16 (UNAUTHENTICATED) belong to the gRPC Status Codes category. 1 indicates that the operation was cancelled, typically by the caller. Meanwhile, 16 means that the request does not have valid authentication credentials for the operation.
描述
The operation was cancelled, typically by the caller.
何时出现
The client explicitly cancelled the RPC, or a deadline or context cancellation propagated to the server before it could finish processing.
如何修复
If unexpected, check whether the client is setting too-short deadlines or if cancellation is being triggered inadvertently in your call chain.
描述
The request does not have valid authentication credentials for the operation.
何时出现
No credentials were provided, or the provided token/certificate is expired or invalid. Different from PERMISSION_DENIED (code 7), which means authenticated but not authorized.
如何修复
Provide valid authentication credentials (e.g., refresh the OAuth token, regenerate the API key, or renew the client certificate).
