UNUSUAL plugin-cln-grpc: Failed to broadcast notification

[Dominion5254]

Issue and Steps to Reproduce

When running CLN 24.08.2 the logs are spammed with the below error:

This error is strange as this is a newly spun up node and I haven't connected to any peers yet. listpeers returns one peer (which presumably was automatically connected to bootstrap the graph?):

Aside from the errors in the logs, CLN seems otherwise healthy. Is is safe to assume this error is benign (as is generally the case with the UNUSUAL plugin-... errors?

Environment

• CLN 24.08.2 running on StartOS 0.3.5~1

Bump. Also seeing this error on a fresh node. I seem to be unable to make outbound payments with my channel to a well connected node. Every once in a while, a payment will go through, but it always fails to route. New to this so not sure if its related. INFO plugin-pay: cmd 34 partid 12: failed: WIRE_TEMPORARY_CHANNEL_FAILURE (reply from remote)
