Webpack build refers to absolute paths in local file system

Question

I am building add-in for MS Word using office js. They provide you with starter-kits and I have built it using their react-starter. It includes a webpack configuration which I have kept pretty much the same. I added an svg-loader and a copy. It is included below.

My issue is that after I build for production some compiled files in the dist folder are referring to absolute paths on my own local computer file system. What is causing this problem?

[Edit: I created a fresh office js react add-in project to see if I get the same issue. And yes, it is still referring to absolute paths.]

(dist/taskpane.js)

reactHotLoaderGlobal?reactHotLoaderGlobal.default:void 0;if(e){var n=void 0!==r?r:t;if(n)if("function"!=typeof n){for(var o in n)if(Object.prototype.hasOwnProperty.call(n,o)){var i=void 0;try{i=n[o]}catch(e){continue}e.register(i,o,"/Users/current_user/app_folder/another_app_folder/src/taskpane/components/Collections/index.ts")}}else e.register(n,"module.exports","/Users/current_user/app_folder/another_app_folder/src/taskpane/components/Collections/index.ts")}}()},25522:function(e,t,n){"use strict";var o=this&&this.__createBinding||(Object.create?function(e,t,n,r){void 0===r&&(r=n);var o=Object.getOwnPropertyDescriptor(t,n);o&&!("get"in

By removing the "react-hot-loader/webpack" from the "tsx"-rule it solved the issue. The absolute path was not included in the build anymore.
