After reading 

https://pro.arcgis.com/en/pro-app/arcpy/data-access/updatecursor-class.htm

I would guess that the second argument has to be a list of field names, i. 
e.

updCursor = arcpy.UpdateCursor(
    projectedFC, 
    ["POINT_X", "POINT_Y"], 
    "",
    spatialRef
)

>     row.POINT_Y = pnt.Y

The goal of the tutor mailing list is to help newbies with the Python 
language, the standard library, and common external packages.

As yours is a specialist topic you will most likely get better answers when 
you ask questions concerning arcgis on a dedicated mailing list or forum.
