It appears that some instances have not resolved the unsubscribes properly, and I'm seeing errors like the below:

2025-10-07T12:20:11.488023Z  WARN Error encountered while processing the incoming HTTP request: lemmy_server::root_span_builder: CommunityHasNoFollowers: CommunityHasNoFollowers
   0: lemmy_apub::activities::community::announce::receive

Is there a way to determine which communities are throwing this error, and force the unsubscribe?

Is that the whole log? Have you enabled the trace level?

This was with the default logging:

RUST_LOG=warn,extism=info,lemmy_server=debug,lemmy_api=debug,lemmy_api_common=debug,lemmy_api_crud=debug,lemmy_apub=debug,lemmy_db_schema=debug,lemmy_db_views=debug,lemmy_routes=debug,lemmy_utils=debug,lemmy_websocket=debug

Any idea which one I should set to trace?
