ERROR: parse error - invalid geometry HINT: "nu" <-- parse error at position 2 within geometry

I know the solution for my problem, but any good reason return string 'null' ?

The output of this function is not intended to be parsed as an actual geometry, it's just meant for sorting with one unique string per grid cell.
