gRPC 1 CANCELLED vs 7 PERMISSION_DENIED
Both gRPC 1 (CANCELLED) and 7 (PERMISSION_DENIED) belong to the gRPC Status Codes category. 1 indicates that the operation was cancelled, typically by the caller. Meanwhile, 7 means that the caller does not have permission to execute the specified operation. This is not for unauthenticated callers — use UNAUTHENTICATED instead.
Description
The operation was cancelled, typically by the caller.
When You See It
The client explicitly cancelled the RPC, or a deadline or context cancellation propagated to the server before it could finish processing.
How to Fix
If unexpected, check whether the client is setting too-short deadlines or if cancellation is being triggered inadvertently in your call chain.
Description
The caller does not have permission to execute the specified operation. This is not for unauthenticated callers — use UNAUTHENTICATED instead.
When You See It
The authenticated user lacks the required role, scope, or policy to perform this action. Different from UNAUTHENTICATED (code 16), which means no credentials at all.
How to Fix
Verify the caller has the correct IAM role, API scope, or access policy. Check RBAC configuration on the server side.
Key Differences
gRPC 1: The operation was cancelled, typically by the caller.
gRPC 7: The caller does not have permission to execute the specified operation. This is not for unauthenticated callers — use UNAUTHENTICATED instead.

When to Use Which
For 1 (CANCELLED): If unexpected, check whether the client is setting too-short deadlines or if cancellation is being triggered inadvertently in your call chain. For 7 (PERMISSION_DENIED): Verify the caller has the correct IAM role, API scope, or access policy. Check RBAC configuration on the server side.
