Getting bug (crashes app completely) related to TransformControls.js’

I just replaced the r175 version with r148 and it was solved. Simple as that.

you need to add the helper now and not the controls.
transformControls.getHelper()

not tested this on v175, but was changed a few versions back

This was changed in r169. All control classes are now derived from the abstract base class Controls. This could be easily changed for all controls expect for TransformControls which was previously derived from Object3D. That was the reason why you could add an instance of TransformControls directly to the scene graph.

As mentioned in the migration guide for r169( see Migration Guide · mrdoob/three.js Wiki · GitHub) and pointed out by @vegarringdal, the line:

scene.add( controls );

has to be changed to:

scene.add( controls.getHelper() );
