Looking at the logs, I was able to pinpoint the issue: a mixup of the paths when creating the Halva packages is causing that error. I am working on a fix for it ASAP.
Double check that the bootstrap is inside the tool's folder -> Bootstrap -> linux. If it isn't and you are on the latest version, let me know and I'll send you a copy of it
That error seems like it was coming from a malformed package.json file. Could you please check if the game's package.json has any issues on it? You'll be able to see it clearly with a code editor like Visual Studio Code.
