1829607 - Internal exception is shown instead of a clear network error request when original file fails loading

Status: RESOLVED FIXED

(DevTools :: Debugger, defect)

• open the debugger on this page
• click from the console on any log coming from a typescript file

You will see a message like this in CodeMirror instead of a clear, actually meaningful message to the user:

Impossible de récupérer la source d’origine : can't assign to property "metadata" on "unsupported protocol for sourcemap request webpack:///client/src/lib/printObjectToConsole/index.ts": not an object
URL de la source : <unknown>

The issue here is that we aren't able to retrieve webpack:///client/src/lib/printObjectToConsole/index.ts from network (and source map doesn't inline this source content)

networkEvent was throwing string exception, which were poorly handled.
