I am constantly getting this error while labelling the PDFs. Earlier it used to work fine.
We are able to train custom model successfully and there is no ongoing outage for Form Recognizer Labeling Tool as below screenshot.
The possible reason for this issue could be your SAS token has been expired. Please check on the connection you are using, update the SAS URL to see if the issue still there. If the issue still block to you, please let us know us with your region and we are willing to help and investigate further. Thanks!
