Console API examples do not work anymore?

[juv]

Hi,

thanks for the interesting project! I am trying out the Console API examples and can not see them have any effect. The city I use is Berlin: https://anvaka.github.io/city-roads/?q=Berlin&areaId=3600062422

After loading the data, I open the developer console and the example in the console line-by-line.

The example Loading all bikeways in the current city fails with an OpenGL error:

[.WebGL-00004BA4022A8700] GL_INVALID_OPERATION: At least one enabled attribute must have a divisor of zero

---

The example Loading all bus routes in the current city fails with the same OpenGL error:

Am I doing something wrong? Thank you!
