Describe the bug / error

We’re using wopiframe.aspx to generate previews for PDF files in our webparts. Until yesterday, everything was functioning as expected. However, today we received several client reports indicating that PDF previews are not displaying properly. We suspect that the gradual rollout across tenants may soon impact more users. Could someone please investigate this issue? Thank you!

The URL format is below :
Using UniqueId:
https://tenant.sharepoint.com/sites/Operations/_layouts/WopiFrame.aspx?sourcedoc={9af85718-3c5a-4fec-9777-bbe609e610ec}&action=interactivepreview
OR using relative Path
https://tenant.sharepoint.com/sites/Operations/_layouts/WopiFrame.aspx?sourcedoc=%2Fsites%2FOperations%2FShared%20Documents%2FRefunds.pdf&action=interactivepreview

Steps to reproduce

1. Upload a PDF file
2. Get the UniqueId of that file or the path
3. Construct the wopiframe.aspx URL
