3.2b1 - Height Map issue "Cannot read property 'add' of null"

[oozeBot]

I've not been able to find a work around for this one. Every since we upgraded to 3.2b1, the Height Map returns the error "Cannot read property 'add' of null". This occurs on multiple PCs running both Chrome and Edge. We've tried dumping our cache but no luck. There is nothing apparently wrong with the height map. I'll attach it to this thread.

I saw another user reported this yesterday as well. If he was able to find a work-around or fix, I am unaware.

Any assistance would be appreciated as this is really starting to hold us up.. Thanks

Are you running with or without an attached SBC?

Just found this error:

HeightMap.vue:499 TypeError: Cannot read property 'add' of null
    at VueComponent.showHeightMap (HeightMap.vue:358)
    at VueComponent.showCSV (HeightMap.vue:303)
    at _callee2$ (HeightMap.vue:494)

Also, I just tried on my iPad and and received: null is not an object (evaluating 'this.three.scene.add').

Although I have not yet managed to reproduce this problem I decided to change the init code, which should fix the problem once and for all. This change will be part of the next v3.2-b2.
