Given the Rolls Royce / premium price of the product, it would seem unusual for Adeunis not to have released an updated JS formatter along with instructions.
But now you’ve got the formatter working (which I formatted as per guidelines) it would be good to see what you have setup for your webhook - as a minimum you need to give it a working URL (ie one that works in a web browser) and click a tick against at least one of the message types.
I’ve seen only one other instance of triggering an error with a Webhook - it may be the destination server is having issues.
