Hello everyone,
Thanks for reaching out to us, there is some change just announced today for this behavior.
Please add the 'Storage Blob Data Contributor' role, it should resolve this issue.
We will add a notification in the doc so that avoiding this error anymore as below -
Please go to Azure Portal, go to the storage account you connected to your Azure Language resource, on the left panel, select Access Control, click the Add button and add the role as the second screenshot.
Add 'storage blob data contributor' role for the user on the storage account even though you are the owner of the storage account.
Please have a try and see how it works, the document team is working on adding more details so that there is less misunderstanding.
Regards,
Yutong
