save_3d_views crashes because javascript's window.viewer.ui doesn't have required attrs #449
Description
I'm not sure if the problem is in the javascript viewer or the python code. Even adding a 5s pause after the first error doesn't really solve the problem. Anyone has ideas on why this is happening?
For now the solution is to re-run the code until it works...which is far from being optimal.
Example error:
