SignRequest module- Not able to get the correct Document URL

Hi
I would like to automatically send out a document via the SignRequest module based on information submitted in a Google Sheet. The process involves auto-generating a Google Document from a template, using the data from the Google Sheet. Once the Google Doc is generated, I will use the SignRequest module to send the document to the signatory for signature via SignRequest.

However, when I add the SignRequest module, I’m unsure how to provide the correct Document URL. Every time I try, the URL seems to not match or work properly. I’m not sure what the problem is. Could you please help me with this?

Error Message
[400] document: Invalid hyperlink - No URL match.
