Parse Error: Expected HTTP/

I had AlarmDecoder working perfectly with my HOOBS 3 setup. Then my Pi died so I got a new HOOBS running newer software, specifically Homebridge 1.3.4 and Node 14.17.6. Now I am getting the following error when starting Homebridge. This is the same setup and config I was using before.

Here is my config with some things *** out:

}

In doing a little more research it appears the newer version of Node is more strict on it’s HTTP parsing. This might be an issue with the Content-Length header from the AlarmDecoder box when sending notifications.
