Wenn ich besagten Befehl ausführe (in der neuesten Developer Version) erhalte ich folgenden Fehler beim Schritt 2 von 3:

```auto

        [webpack-cli] Failed to load '/platform/src/Administration/Resources/app/administration/webpack.config.js' config
        [webpack-cli] Invalid options object. Terser Plugin has been initialized using an options object that does not match the API schema.
         - options has an unknown property 'sourceMap'. These properties are valid:
           object { test?, include?, exclude?, terserOptions?, extractComments?, parallel?, minify? }

```

Hab bereits versucht webpack downzugraden - aber bringt außer anderen Fehlern gar nichts.

Ich hoffe mir kann hier jemand weiterhelfen.  
Danke.
