Enabling Service Bus and SAP built-in connectors for stateful Logic Apps in Standard

Hi Edward, 

This is the message we're facing very often in our Standard Logic Apps deployed under ASEv3. 

{  "code": "ServiceProviderActionFailed",  "message": "The service provider action failed with error code 'ServiceOperationContextUnavailable' and error message 'The call to retrieve the action context has timed out. This could be due to a scale-in event. Please try adjusting the auto-scale settings for this logic app to fix the number of active instances.'."}

We have also specified {"properties": {"vnetPrivatePortsCount": "2"}} and still having this issue.

Please advise.

Thanks
