inferno: Creating Component vNodes using createVNode is not allowed (inferno4)

I am trying to convert my inferno v3 component to v4 and I have problem with this error:

Inferno Error: Creating Component vNodes using createVNode is not allowed. Use Inferno.createComponentVNode method.

What is guideline for replacing createVNode with createComponentVNode in inferno 4 ? Should I use createComponentVNode only if type is Component and createVNode for everything else? if so, why this code throw Error? createVNode(2, 'div', props); type 2 is HTMLElement.

BTW, this is where I am trying to make it works: https://github.com/infernojs/inferno-transition-group/blob/next/src/TransitionGroup.js#L176
