Even if we override the webpack output.filename or output.path, the command electron-webpack dev will still try to load the dist directory for main/main.js. I think it should also try to run the output file from the persisting webpack config, after overrides.

In my case I configured the output to build/tmp since that has been the directory structure for almost all of the node apps. I used this method for overriding: Modifying Webpack Configurations
