Browser debugging breaks in multi-module MPP project

Hi, previously I have been using the in-browser debugger for my MPP project, however browser debugging breaks when that repo was ported over as a module in a multi-module project. The only discernible difference between the two are the folder structure, as the aforementioned repo is nested one level down from the root.

Folder structure difference: Upload ID: 2021_09_23_H9Ejd1723dKxWdPM

The in-browser error in Firefox is as follows:

`Error while fetching an original source: NetworkError when attempting to fetch resource.
Source URL: webpack://sourceUrl`

It leads me to believe this is a 404 error.
Attempted fixes:

• Changed webpack config's `devToolFilenameTemplate` property.
• Downgraded webpack version from 5.*.* to 4.44.1
• Changed webpack loader
• Manually configure source map URLS
• Added custom eval-source-map plugin to change source map path
