Unable to parse WKT string

[polizz]

The wkt POLYGON((-89.31029407 38.72017071,-89.30548017 38.72017071,-89.30421905 38.72418814,-89.31029407 38.72376013,-89.31029407 38.72017071))

causes parse to throw the following error:

via:

wkx.Geometry.parse('POLYGON((-89.31029407 38.72017071,-89.30548017 38.72017071,-89.30421905 38.72418814,-89.31029407 38.72376013,-89.31029407 38.72017071))')

Can you let me know what I'm doing wrong?

I've tested your wkt with node 12.x and in Chrome, but couldn't reproduce it.
