Recieving {"error":9} when addressing 127th individual LED via json API

I’m trying to use the json API to activate individual LED’s. I only have the single segment that is active by default. I am using the json API, and providing a json file to the -d curl flag.

I have a 16x16 LED sheet attached to an ESP8266 module, for a total of 256 individual LED’s. The json files I have are addressing each led, per documentation HERE. I’m able to address up to LED 127 with no problem, but then receive {“error”:9} in the response.

Is there a limit to how many LED’s can be addressed at once? Is there a better way to have a map of LED’s that I can push at-will? The final goal is to basically have a ‘bitmap’ that I can have push to WLED from home automation.

Here is the file I’m using that gives the error. Removing LED 127 from the top will allow it to work:
