I'm having the same issue while trying to draw a polyline. I have a UIKit map and SwiftUI map, and both are failing to draw the "path" of the user (not showing). My console gets full of these "Compiler failed to build request" logs. If I comment out the one-line of code that sets the stroke color of the polyline, the error disappears, but the "path" is still missing. Any ideas? Thanks in advance!
