By default chrome extension's resources has no web accessible. If debug chrome-extension source map, You should add manifest declaration at manifest.json. Use the web_accessible_resources manifest property to declare which resources are exposed.

{
  "name": "hello world",
  "description": "",
  "version": "1.0",
  "manifest_version": 3,
  "web_accessible_resources": [
    {
        "resources": [ "sourceMap/*" ],
        "matches": [ "<all_urls>" ]
    }
  ]
}
