Use API to restoreVersion - 401 Unauthorized error

Hi,

I am trying to use Flow to restore previous version of all items on a list.

The documentation about this API is below:

https://docs.microsoft.com/en-us/onedrive/developer/rest-api/api/listitemversion_restore?view=odsp-graph-online

I believe this step is constructed properly.

But, as I run it, I got the below error:

How/Where should permission be set? Is it about the user (i.e. myself)? or the list?

Thanks.

Dchan

Please check if you have a space in front of the Uri. I got the same problem and I fixed the issue by deleting a "hard-to-see" space at the beginning of the Uri.
