I have two related Zaps for a Docusign template. One creates a new GoogleSheet row for each time the template is used. The other updates the specific GoogleSheet row when the Docusign envelope is completed, and uploads a copy of the completed envelope to a folder on our shared Google Drive. At the “File” step in the Zap, I selected the trigger step “Envelope Completed in Docusign” and the field “Envelope Combined Document (Exists but not shown)”.
I set this up at the end of March, and it has been working perfectly until about a week ago, when I suddenly started getting an error at the File step (which is the step that uploads the completed file to the drive). The error is “Required field “file” (file) is missing”.
I cannot understand why this would suddenly stop working when I have made no changes to it or any of the related programs. I checked to make sure that Zapier and Docusign both have the needed access to the shared Google Drive and they do. I am pulling my hair out. Please help.
