Exception thrown when trying to migrate file storage to Azure Storage account

Former Member

I'm trying to migrate the file storage for our community to Azure Blob Storage following the guide here -  How Do I Migrate My Existing File Storage to Azure? 

I've carried out all the steps according to the documentation, but when the migration job runs I get an exception.

The error from the logs is:2022-05-23 09:20:00,319 ERROR [27] - Error occured executing job 'Centralized File Storage Migration Job (Id=03cc08a5-2548-479a-aad1-caa25c012dbf, JobId=e5c983e6-05a3-436f-948d-b7d26cfd9f9a, Platform=evolution) ExecutionTimeUtc: 5/23/2022 9:20:00 AM': UnknownException: Exception occured while running background job (Centralized File Storage Migration Job (Id=03cc08a5-2548-479a-aad1-caa25c012dbf, JobId=e5c983e6-05a3-436f-948d-b7d26cfd9f9a, Platform=evolution) ExecutionTimeUtc: 5/23/2022 9:20:00 AM).

Does anyone know if there is a fix for this?

Thanks

    I would contact support and open a ticket, specifically make sure you are running the correct version of the azure components for your version.

    Actually, please check the How Do I Migrate My Existing File Storage to Azure? again as we've updated the download links. The page you referenced includes download links as well as the the general doc (non-migrating) on  deploying to azure  and they were out of sync.

    I've downloaded the right versions of the Azure components and run the migration job. It looks like everything has uploaded to blob storage. but it seems to be having problems downloading some of the assets from the themefiles folder.

    I'm getting placeholder images where some font characters would be used, for example, the "magnifying glass"  in the search box

    Looking in the monitoring section of the administration portal, I can see an exception being thrown trying to retrieve entypo.woff

    and the stacktrace is:

    UnknownException: An error occurred while serving a local CFS file (An unexpected error prevented your requested action from completing. The error has been logged for the administrator to review.) ---> System.NullReferenceException: Object reference not set to an instance of an object.
