Hi @shubhamdubey,
First thing to check: go to Hermes Messaging Service > Diagnostics and run it for whatever service your log producer points at. A common documented state there is "Hermes is installed but isn't fully configured yet for service: <service name>", and if that comes back for your service, it fully explains an empty Topic Inspector, the topic list is empty because Hermes itself hasn't finished activating for that service, not because your log source is wrong.
Second thing, and honestly the more likely culprit given your screenshot: the Select Service dropdown in the Topic Inspector lists every Hermes service registered on the instance, not just the one Log Export Service created for your source. uxa-sync-service is a separate Hermes consumer used for a different sync/replication flow, so pointing List Topics at it will always come back "No Topics To Display" no matter how correctly your Log Producer is configured. Go back into the Log Export Service setup and confirm the exact service name tied to the source you configured in step one, then select that same service here.
On top of that, a Hermes topic only gets created once the source actually exports its first log record, so also confirm the underlying Log Source record is Active and its filter is actually matching something, otherwise you'll see nothing even against the right service.
Share the exact service and log source name from your setup and I can help narrow it down further.
