buildFromPolygon throws std::length_error

[janis-github]

Here is the source:

await SkeletonBuilder.init()

const data = [
  [7481, 274],
  [10509, 115],
  [10555, 964],
  [7481, 1126],
  [7481, 1866],
  [4356, 1866],
  [4356, -1896],
  [7481, -1896],
  [7481, 274],
]

SkeletonBuilder.buildFromPolygon([data])

It produces the following error:

Uncaught P std::length_error: vector

Would it be possible to know why this happens? Maybe there is something specific with the polygon what triggers it that would suggest a workaround?

This polygon works fine:

const data = [
  [7481, 274],
  [10509, 215],  // changing 115 to 215 here fixes the crash!
  [10555, 964],
  [7481, 1126],
  [7481, 1866],
  [4356, 1866],
  [4356, -1896],
  [7481, -1896],
  [7481, 274],
