Hey @arkonis!
It seems as though the key here might be what you pass to the DeleteUser query as additionalScope. Since it looks like you only need the UID here can you try declaring rows as just an array of the UIDs in your table using one of the following?
var rows = formatDataAsObject(userTable.data).uid;
var rows = userTable.data.uid;
It may be the case that you need a different syntax here. If you can share a screenshot of some of your table data expanded in your debug console we can help grab the exact syntax you need.
