Compound body, shape collision events

[IRobot1]

I'm working on a VR keyboard component using physics collisions to trigger a key press.

   declare type BodyShape = BodyProps & { type: ShapeType; };

    const shapes: Array<BodyShape> = [];

    // create trigger volumes for all the keys
    this.keys.forEach(item => {
      const size = makeVector3(item.size);

      const props: BoxProps = {
        isTrigger: true,
        args: makeVector3([0.2, 0.1, 0.2]).multiply(size).toArray(),
        position: item.position,
        onCollide: (e: any) => {
          console.warn('onCollideBegin', e);
        } 
      } as BoxProps;

      shapes.push({ ...props, type: 'Box' } as BodyShape)
    })

    this.body = this.physicBody.useCompoundBody(() => ({
      position: this.position,
      rotation: this.rotation,
      shapes: shapes
    }));

When the app starts, I get the following error in the console

Uncaught DOMException: Failed to execute 'postMessage' on 'Worker': (e) => {
                    console.warn('onCollideBegin', e);
                } could not be cloned.

Does the underlying Cannon Worker support collision events in shape definitions within a compound body?

If not, they need removing from the shape type definitions to catch this mistake at build time.
