Issue with Azure Blob Store integration as AEM data Store

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.

Hi gauravb10066713​

I had seen the page earlier also. It did not help much. After that comment there is no relevant comment.

Hellosmacdonald2008​

Yes, I did follow all the steps except the extra parameters set-up under the section "Besides the settings above, the following settings can also be configured:".

This is AEM 6.4 new instance with no custom code or content installed on it. Since it is not for production, did not raise any support ticket. Sent email to SPP_Help and awaiting.

If anyone else has found any solution please share.

Thanks
