Hi @KMLAU_MOORE,
I have done some testing with the Basic Approval template and the Notes table.
Can you try the below approach instead?
1. Extraction of the URI of the persons OneDrive site, based on the notetext attribute value
concat(split(outputs('Get_a_row_by_ID')?['body/notetext'], '/')[0],'/',split(outputs('Get_a_row_by_ID')?['body/notetext'], '/')[1],'/',split(outputs('Get_a_row_by_ID')?['body/notetext'], '/')[2],'/',split(outputs('Get_a_row_by_ID')?['body/notetext'], '/')[5],'/',split(outputs('Get_a_row_by_ID')?['body/notetext'], '/')[6])
File Path
Documents/Approvals Document/@{outputs('Get_a_row_by_ID')?['body/subject']}
