Start with app/components/Exchange/TradingViewPriceChart.jsx and inspect the import or lookup for ../../../charting_library/charting_library.min.js. Run the reported npm development build and trace the missing module through the listed Exchange entry points; done means webpack compiles without this module-not-found error.
