MsGraph PDF Converter Always Returns 404, Even When the File Exists and is in the Correct Directory

We have a Power Automate flow that calls the Microsoft Graph API using the access token generated from the app registration with the correct API permissions. The process follows these steps: get the access token, get the site ID, get the drive ID, get the drive item ID, and finally get the PDF version of the file, all in API calls. The PPTX to PDF conversion worked for 4 weeks but suddenly started failing, always returning a 404 error, even though the file exists and no changes were made to the PPTX template or site permissions.

    Hi @MERSAN CANONIGO JR

    I just did a quick test locally and it worked fine for me.

    Could you please share some screenshots of your test so I can analyze the cause of the error?
