Error creating images from renderer

[Jakobabs]

I'm trying to save a png from the renderer using the example "offscreen-render.html"
Everything works copying the script, but when I change the camera position/rotation other than what is in the example, skinViewer.canvas.toDataURL() results in a blank image. Here is my code:

export async function get_image(skin, cape, arms) {
  const skinViewer = new SkinViewer({
    width: 200,
    height: 300,
    renderPaused: true
  })
  skinViewer.camera.rotation.x = -0.620
  skinViewer.camera.rotation.y = 0.534
  skinViewer.camera.rotation.z = 0.348
  skinViewer.camera.position.x = 30.5
  skinViewer.camera.position.y = 22.0
  skinViewer.camera.position.z = 42.0

  await skinViewer.loadSkin(skin, { model: arms })
  await skinViewer.loadCape(cape)
    
  skinViewer.render()
  const image = skinViewer.canvas.toDataURL()
  skinViewer.dispose()
  return image
}

Does anyone know why changing camera position x to -30.5 breaks the code?
