web-app broke while editing kcl

[mlfarrell]

current kcl code some variant of:
was editing around line 19

fn square(x, y, l, prevSegment, theta) {
  pl = if l > 0.0001 {
    l - 0.05
  } else {
    0.1
  }

  squareSketch = startProfileAt([x, y], prevSegment)
    |> angledLine({ angle = theta, length = pl }, %)
    |> angledLine({ angle = theta + 90, length = pl }, %)
    |> angledLine({ angle = theta + 180, length = pl }, %)
    |> angledLine({ angle = theta + 270, length = pl }, %)
  return squareSketch
}

fn box(plane, start, l, lMin) {
  x = start[0]
  y = start[1]
  box = startSketchOn(box, )
    |> square(x, y, max(l, lMin), %, 0)
  // |> extrude(length = max(h,hMin))
  return box
