I’m trying to use “Populate a Microsoft Word Template” to insert a signature image into an already existing Word document in SharePoint, but I keep getting a “NotFound” or “The provided workflow action input is not valid” error. I’m already using Get file properties and selecting the Id for the file or used Get file content using path , but it still doesn’t work. What is the correct way to update an existing Word document with an image in Power Automate?
