Try Event Hub and add logger to APIM but nothing get logged

Hi, I've followed api-management-howto-log-event-hubs to use Event Hub, add logger on APIM but with no luck, nothing get logged.
The logger seems created successfully, I can get it via API.
After comparing it with sample response, I'm suspicious the cause is the returned NULL "resourceId" but cannot figure out which part I'm missing.

Here's my request body for logger creation.
