stackrabbit.lua:276: Failed to parse game state from response error

so im getting an error stackrabbit.lua:276 and have no idea how to fix it. I followed the Steps of how to run the AI. i have Node.js v26.5.0, FCEUX 2.7.0 (Win64) and visual studio community 2026. i did the cd path/to/stackrabbit, Run node install.js, i did had some vulnerabilities installing node had to do the -force to fix it, after 0 vulnerabilities i ran npm start and it works (Listening on port 3000). Next I open the FCEUX loadup TetrisGYM, got the cursor on level 19, ran the stackrabbit.lua script, AI was doing its thing like 10 secs sometimes longer MAX of 3 mins. idk if its the localhost:3000 or having the 3 programs the wrong version.

Start at stackrabbit.lua:276 and inspect the response returned from localhost:3000 while npm start is listening. Reproduce with FCEUX 2.7.0, Node.js v26.5.0, and the TetrisGYM setup described, then check whether the response is valid game-state data. Done means documenting the cause and a verified compatible setup or fix.
