SharePoint lists with Copilot Studio error
troyho You’re seeing this error because Copilot Studio is having trouble using the SharePoint link you entered.
A few things to check:
- Use a SharePoint site or library link, not a direct link to a single file (for example, use the site like .../sites/YourSite, not the .docx file itself).
- Make sure you’re signed in with an account that has permission to read that SharePoint site and its files.
- If the file is very large, Copilot Studio might not be able to use it.
I also ran into a similar issue myself: I had set the agent’s Authentication setting to No authentication and then tried to connect a SharePoint file. Because “No authentication” doesn’t allow Copilot Studio to read SharePoint or OneDrive content, I got an error. I fixed it by switching the authentication to a supported option (for example, Authenticate with Microsoft or manual authentication), and after that the SharePoint file connected and worked correctly.
For a step‑by‑step guide and all the technical details, please see Microsoft’s official article:
