I have published couple of APIs through APIM. Now I try to read some diagnostic logs. While I choose APIM -> Logs -> API Management services -> ApiManagementGatewayLogs -> preview data
or fire query:
That error indicates the table hasn't been created, yet.
1. You need to wait a few hours and APIM has to send some data for it to create a Table
2. Are you using the same workspace as you configured in the Diagnostic logging?
