Help needed: Signed documents via Power Automate needs password to view.

On Wednesday afternoon the workflow was still working correctly. I was on leave for one day and this morning the documents that are signed is comming back requiring a password to be viewed.

Details:

The document is uploaded and sent for signatures via Power Automate and this is still working fine.

The worklfow then wait for the document to be signed before saving it to SharePoint, but when we try to open the pdf it needs a password to view the document. (The copy of the pdf that is sent via email to the signer is working correctly and does not need a password to view.)

I checked the "Document Password" field on the "Create an agreement from an uploaded document and send for signature" action but it is empty. Passing "null" also does not fix the problem.

Any ideas?
