App crashes at uniforms.fogColor.value.copy( fog.color ); when uniforms.fogColor.value is null

[lorikou]

Description:
I have written an web game-application with a-frame and I'm using -among others - the aframe particle system component along with the aframe environment component .
When rendering an entity that includes the aframe particle system component my app crashes and I get the following error:

This issue is resolved if I change the following line in aframe-master.js (line 32470)
uniforms.fogColor.value.copy( fog.color );
with this
if ( uniforms.fogColor.value ) uniforms.fogColor.value.copy( fog.color );
But that way the error will not be fixed permanently since it will be reproduced everytime someone reinstalls the npm packages.

I actually did manage to reproduce the error here (glitch). However this time the error is thrown directly from three.js. The app works just fine after I remove the component from the environment entity.

I quickly found that a newer version of the component called aframe-particle-system-component-fog-fix has been released, which supposedly exposes only a subset of the ShaderParticleEngine API. I had not made the switch, but after uninstalling the old one and installing the new, nothing changed.

Can somebody help me fix this?
