This happens to me on the Server too https://webarstudio.tripod-digital.co.nz/ (so master branch) Do you receive this error?
I thught that was only my issue in the PR #1 but it seems that i was wrong...

To be precise: the error is displayed when you point the pinball marker to the camera. I will look into it.
