Problem processing your document

Hello,

So, I'm trying to create a Power Automate flow to send a document for e-sign via Adobe Sign.

The automate task should trigger uppon receiving a new item in a list, grab the attached file and send it over for signature.

But I'm gettin an e-mail stating that it were unable to create the agreement because it had a problem processing the document.

Do I need to set something up in the document beforehand?
