Text Classification Sample - Authorization Permission Mismatch in Lanugage Studio

Question

In the custom text classification, you upload the test data files into a storage blob.

I have followed the documentation for providing the roles on the storage blob for the language studio service but I continue to get the following error:

<?xml version="1.0" encoding="utf-8"?><Error><Code>AuthorizationPermissionMismatch</Code><Message>This request is not authorized to perform this operation using this permission. RequestId:011518c5-101e-0053-34e6-db48fc000000 Time:2021-11-17T19:06:58.8246891Z</Message></Error>

I'm not sure how else to proceed to figure out why this is not working. Clearly it's the permissions or roles but we seem to have set them as described in the documentation.

Hello

I have seen error and the error for me is the CORS setting of my storage account is not correct. I add a new rule for my storage account .

Configure cross-domain resource sharing (CORS) on the Azure Storage blob Enable CORS on your storage account. Select your storage account in the Azure portal and then choose the CORS tab on the left pane. On the bottom line, fill in the following values. Select Save at the top.

Allowed origins =
Allowed methods = [select all]
Allowed headers =
Exposed headers = *
Max age = 200 (here I am using 1800, but 200 should be enough)

Then everything works fine for me. Besides that, please make sure your storage account is under Standard performance and your container is Public access level to Container (anonymous read access for containers and blobs).

Hope this will help. Please let us know if any further queries.

Answer 2

I had the same problem. I contacted support but got a bit vague answer, that indicates that default settings when setting up the Language Service and the storage service is wrong.

I got it solved by adding Storage Blob Data Contributor to My user or the user that experience the issue in the Language Studio.

1. Go to the Access Control (IAM)
2. Press Add
3. Find Storage Blob Data Contributor
4. Locate the User (The user you login to the Language studio)
5. Review + assign

Then signout of all sessions and login again to refresh tokens
