New AzEventHubs library not using $Default as the default consumer group #43049
Description
Component(s)
receiver/azureeventhub
What happened?
Description
Using the new feature flag / SDK with the Azure Event Hubs receiver, the consumer group no longer defaults to $Default if no consumer group is set. It should be a seamless update to the new SDK from the old one.
Steps to Reproduce
Run the collector with a simple pipeline using the new SDK feature flag
receiver.azureeventhubreceiver.UseAzeventhubs without the group config option set.
Expected Result
The collector successfully starts and begins collecting logs from Azure Event Hubs with the $Default consumer group
Actual Result
Error:
