I'm trying to use web workers in my project. It works fine in the dev mode but failed after the build.

Uncaught DOMException: 
Failed to execute 'importScripts' on 'WorkerGlobalScope': The script at 'http://localhost:4000/js/js/vendor.4a4f636a.js' failed to load.

The file structure is shown as follow

It seems that an extra "js/" is added in the link. The correct link for the script file should be http://localhost:4000/js/vendor.4a4f636a.js

To reproduce, I create a small repo. Strangely, it works after removing the for loop in src/worker/load_data.js.

Have I done something wrong? Are there any configurations needed to make this work?
