I get this error when using the Update Document action. My SharePoint 2013 onPrem Word Automation Services Web Application is created and working.
For source URL I have hard coded the URL to a .docx document in a document library.
The document has a single content control which I am referencing and populating with a list item variable.
The Output URL is a variable that points the what I want the document to be called in a document library. I generate the variable value using a Build String action. However, I still get this error when when I hard code the name of the file for the output URL.
This should work but I get the error: Error converting document. Invalid URI: The format of the URI could not be determined.
