Hi! I have a question about authorization. If we use static_user_provider we cant start flownode. It fails with error:

The request does not have valid authentication credentials, source: 0: Not found http or grpc authorization header, at src/client/src/error.rs:173:1
2026-07-17T13:26:30.462954537-04:00 stderr F Error: 0: Failed to start flownode, at src/cmd/src/flownode.rs:96:37

Greptimedb 1.1.2 Can you advice correct config for flownode please?

hello, @Denys Zorinets, please enable this internal grpc configruation on frontend as described in the note section docs.greptime.com/reference/command-lines/flownode#… We provide an internal grpc port for flownode to communicate with frontend without need for authentication. This should be enabled by default with our helm chart.

Worked like a charm. Thank you!
