Hi,
I'm trying to use the technique in this video to create site pages based on a list item in another SP site.
https://www.youtube.com/watch?v=QtBqeEEOgdE
The use case I have is that I have a list with normalized data I want to turn into site pages. Where my flow is getting stuck is on the step where it needs to call the Template in my SP site that will determine the layout.
I'm getting this error.

The raw output looks like this.

"errors": [

}
}
On the surface, it looks like I don't have permissions in the Sharepoint Site where the template lives, but I do. I'm the owner of the site and the super admin for my tenant. Technically, my account should have permission to do anything and everything, but I know that's not the case.
Where do I go from here?
