Hello @Satvik Srivastava , Thanks for using Microsoft Q&A Platform.

As per the error message looks like there is an issue with the Shared Access Signature (SAS) token used to authenticate the request to Azure Storage. This error can occur if the SAS token has expired or invalid. Please follow the steps outlined in the on regenerating a SAS token.

Also, can check if the Azure Storage account used has the necessary permissions like "Storage Blob Data Contributor" role assigned to it. You can check and assign roles to the storage account by following the steps outlined on managing access to Azure Storage resources.

EDITED:

Ah! Yep I went back to have just the one data labeling project. And the the (DatasetCorrupt) with SAS authentication error has gone away!

anything you do in particular that fixed it?

EDIT: I deleted the dataset and added it again. Then I imported my coco file from blob storage and it worked without throwing the error.
