I’m new to Power Automate. I built a flow with Copilot that:
- Prompts for a SharePoint source folder
- Lets the user select specific files from that folder
- Prompts for a destination UNC path and copies files to that network share
The List folder action fails. I edited it to select the Site Address and the File Identifier (folder path) via the picker and after clicking the Save button getting an error.
Error (from Run history):
I confirmed the folder exists and I have access. What am I missing—should I use a folder path vs. file identifier, or is my library name wrong? Any known issues with “List folder” and library names like “Shared Documents”?
Error :
Message = Object reference not set to an instance of an object.
Error = System.NullReferenceException
