I've installed Weblink 10.2 on my development workstation. 

Windows 10

Visual Studio 2019 updated to newest version

The application runs and works fine via my local instance of IIS.

However, if I go to the web.config and set the compilation node's debug property to "true" the application experiences errors.  I'm gettting errors like the following in the Chrome console:

Failed to load resource: the server responded with a status of 404 (Not Found)
vendors.min.js?v=10.2:1 (SystemJS) XHR error (404 Not Found) loading http://localhost/WebLink/app/welcome/welcome-main.js
    Error: XHR error (404 Not Found) loading http://localhost/WebLink/app/welcome/welcome-main.js
    Error loading http://localhost/WebLink/app/welcome/welcome-main.js

(the files are there)

This happens to the unmodified WebLink app.  This also happens with a version I successfully compile myself in Visual Studio with a debug configuration.

Simply changing that setting back to "false" makes everything work again.  

So, I cannot debug the app in Visual Studio.  What am I missing?

Update 3/22/2021

Just to eliminate it being a workstation issue, I moved WebLink to a test web server.  On a Windows 2008 R2 Server I am experiencing the same issue.  Setting debug to true makes the application not run.  Am I the only person experiencing this?  Any ideas?
