Got to Chapter 4 and tried to make an alchemical laser, following the example in the ponder. But nothing happened when the deployer punched the machine.

Ran /kubejs errors and found a long string of these:

[23:30:11] [ERR ] Error occurred while handling event 'block.left_click': TypeError: Cannot find function getOpposite in object east. (server_scripts:bonkers_chemistry.js#529)

Commenting out that line and the following return line results in the firework sound playing when the deployer punches the frame but there is no other effect, neither particle effects nor any attack damage and no effect on a hopper minecart's contents in line of sight of the lamp.

This started working after I updated a few mods to the most recent stable versions, including KubeJS and Rhino.
