Custom Vision Publish Error: AuthorizationFailed on Storage Encryption Scopes

Hi everyone,

I'm having a very frustrating issue trying to publish a Custom Vision model, and I keep getting the same AuthorizationFailed error every time.

Here is the exact error message:

"error":{"code":"AuthorizationFailed","message":"The client '*****' with object id '' does not have authorization to perform action 'Microsoft.Storage/storageAccounts/encryptionScopes/read' over scope '/subscription//resourceGroups/iris-UKSouth-prod-data/providers/Microsoft.Storage/storageAccounts/irisprodukspredictions/encryptionScopes/****' or the scope is invalid."

What I'm doing:

• I built a Custom Vision Object Detection Model.
• When I click Publish and choose my prediction resource (PlatformationLogoDetection-Prediction), the publish operation fails instantly with the error above.

What’s confusing:

• I cannot see the storage account mentioned in the error (irisprodukspredictions) anywhere in my subscription.
• I have Developer Support and Contributor access on my subscription.
• My Storage Accounts page shows zero storage accounts.
• It looks like Custom Vision is pointing to a storage account in a completely different subscription (iris-UKSouth-prod-data), which I don’t have permission to view.
• Because of this, the service cannot read encryption scopes and the publish fails.

What I’ve tried:

• Checked region alignment (all UK South).
• Checked IAM access on my resources.
• Recreated the Custom Vision resources.
• Tried multiple publish attempts.
• Tried creating a support request in Azure Portal, but I keep getting sent into troubleshooters and cannot reach the real support ticket wizard.

My question:

Why is Custom Vision trying to read encryption scopes from a storage account I cannot access, and how can I give myself (or the Custom Vision service) the correct RBAC permissions?

Any help would be really appreciated - this is blocking me from deploying my model.

Best regards,
Noah
