Steps to reproduce

1. yarn install
2. yarn start

It does not happen with a minimal electron app. I depend on a library in a monorepo, with package.json dependencies saying foolib: "../foolib" . No idea whether that is the cause or not.

[benbucksch]

Same problem with electron-vite / electron-builder, so most likely not a bug in electron-forge, but in the app.
Unfortunately, the error message is patently unhelpful and blames the build system.

Can you provide a minimal reproduction repo with electron-vite ?
Perhaps the options.baseDir makes sense. 🤔

forge/packages/plugin/vite/src/Config.ts

Lines 27 to 29 in b0cae41

	// Reserved option, may support modification in the future.
	// @defaultValue '.vite'
	// baseDir?: string;
