Cannot read property 'numGeoms' and onDemandLoadingEnabled

I followed modelderivative project and got a urn of a model. I uncommented the code you mentioned in the readme. Earlier I had used this project successfully and I was able to see the model in the viewer. Now when I run I get following errors >

This hurts performance. Check the Content-Encoding header returned by the server and check whether you're getting double-compressed streams. The warning prints only once but it's likely the problem affects multiple resources.

Which version of the viewer are you using? Check in the console by typing LMV_VIEWER_VERSION

That can give me a better idea of what is happening. Thanks

LMV_VIEWER_VERSION "2.17" Later on I restarted my system and it started working :)

Ok cool, Yeah maybe a cache problem. Let me know if it happens again. Cheers!
