Hello,
We are trying to configure Azure Blob Store as an AEM external data store following the document here - Configuring node stores and data stores in AEM 6
However, it seems the data store is not working as expected because the AzureDataStoreService is not started properly.
When we checked we found below exception in error.log

Anyone faced this error? Any idea how to resolve this.
Since this is not working, AEM by default using the datastore within the repository as a fallback option. But we would like to use the Azure Blob store for Asset storage.
