私の電極アプリの初期状態を別のAPIへのhttp呼び出しで設定しようとしています。私は、http要求を作成し、要求にエラーのないデータがあるときに解決する約束を返すgetLatestProducts関数を書きました。私はcreateReduxStore関数から約束を返さなければならないことを知っていますが、このエラーを消すための約束をどこで解決すべきか分かりません。ReduxRouterEngineエラー：TypeError：未定義の 'then'プロパティを読み取ることができません
Electrode ReduxRouterEngine Error: TypeError: Cannot read property 'then' of undefined
