Getting full url path of nested folders and file inside "Dcouments" in a sharepoint site

I'm using Flow to get the full path of nested folders and files inside "Documents" in a SharePoint site.

The ultimate goal is to verify which paths are more than the character limit of Microsoft. 

It is a simple flow, but the thing is, I'm not getting a folder path under the "Document" folder, but I'm getting a path under "Shared Document". 
As per the org requirement, I could not disable the shared document feature in SharePoint. 

Is there a way to do it? (I don't mind to use flow or PNP script )
