Have tried this in two environments without success just to be sure I'm not losing the plot.

Permission Error is 401: Unauthorised but the connection is a SharePoint Admin in both cases which makes me think it's something to do with the URI request or the Headers.

Flow Objectives / Actions

Manually Trigger
Copy folder (with subfolders and files)
1. Works Fine
HTTP Request to remove permissions and stop inheriting permissions
1. Needs to apply to the parent folder, and folders and files within
2. Where the issue is, see below.
Apply new permissions
1. Can't get to this because flow fails at step two

I just moved to new builder and now I am getting an error with one of the headers that I wasn't before.

The upside is there is now more information about the error but I still don't know how to fix.

It appears that the 'uri' parameter in the 'Send an HTTP request to SharePoint' action is referencing a SharePoint API endpoint that requires authentication, but the 'Authorization' header is missing or empty. Double-check that the 'Authorization' header is correctly set with a valid access token or authentication token.
