Reproduziere den Build mit webpack@5.10.0, optimize-plugin@1.0.0 und Node v15.2.0 und verfolge dann den Stacktrace durch die generierte Datei assets/~containers~a~count~cash-114e7fb5.js sowie die angezeigten optimize-plugin/@babel/traverse-Pfade. Als abgeschlossen gilt die Aufgabe, wenn der gemeldete Build ohne den TypeError abgeschlossen wird.
