I keep getting the following error when I try to calculate cross-section stationing:

"Calculating cross-sections stationing...

InternalError("line_locate_point: 2st arg isn't a point\n",)"

What could cause this error?  I modeled two other streams using the exact same process as on this one without issue.  Stream centerlines, cross-sections, and flowpaths were all drawn by hand in the correct direction.  The latter two were drawn, deleted, and then redrawn, yet the issue persists.  Also, cross-sections intersect flowpath lines only once.

I'm using QGIS 2.18.17, PostgreSQL 10.3, PostGIS 2.4.3, and Windows 10.
