Azure datalake connector gen2

Hi @ amackenzie ,
I followed this video to create the connector:
How to Connect PubSub+ to Azure Data Lake Storage (Gen 2)
How to Connect PubSub+ to Azure Data Lake Storage (Gen 2)
Connector creation was successful and I did not have any issue. Everthing seems up.
Now when I see the stats , I see the stats of rest consumer it says that :“REST consumer is disabled”.
And error reason is “Missing OAuth2 Token”. I am pretty sure that Oauth 2 details I provided were correct.
I do not know what I did wrong.
