Please upvote this thread if you need this action to have support for when AzureWebjobsStorage value is a keyvault secretUri.

The current deployment is dependent on AzureWebJobsStorage for getting AccountKey and AccountName. There will be more investigation needed to access the storage account with keyvault secretUri. On adding support for using keyvault secretUri, users will need to use RBAC auth option for their workflow.
