Hello
I have the same issues, can't upgrade an project and can't use the auto label feature, both times I get the same errors as @Colin McNelis.
Further informations to my setup: The storage account is configured with restricted access and the Document Intelligence has a system assigned managed identity configured with Storage Blob Data Contributor to the storage account (as stated in the documentation : https://learn.microsoft.com/en-us/azure/ai-services/document-intelligence/managed-identities?view=doc-intel-3.1.0)
