JSON Configuration Error

I'm getting a JSON configuration error once the JSON file is loaded. The Zoom software accepts the file with no errors but after 30 seconds the error message pops up " JSON Configuration error".

This file is to add 3 buttons onto the Zoom Panel interface. We need to send serial strings via IP to a Lightware device. This Lightware device sends the commands out of its com port to a TV mount com port to control a TV mount. We can ping the Lighware device no problem.

Here is the syntax:

],
