[object%20Object] が表示される

いつもお世話になっております

現在、ECサイトのモックアップを作成しております

問題
・Detailボタンをクリックすると、urlに"/orders/ここにOrderID/"と表示されるところが、"http://localhost:8080/orders/[object%20Object]"となってしまい、何も表示されません

目標
・URLにOrderIDが０の列のDetailボタンをクリックすると、OrderDetailページに飛び、そのときのURLが"orderｓ/0"となること
・列0をクリックしたなら、０の中身だけOrderDetailページに表示される

試したこと
・キャッシュの削除
・再度npm run serve

Vue.jsは最近触り始めたばかりで、POSTやGET、axiosの使い方もまだ良くわかっていません。詳しい方がいれば、ご教授お願いします。

写真１My Orders のページ↓　ここでDetailボタンをクリックすると、写真２に飛びます

写真２OrderDetail のページ↓

<b-button variant="dark" :to=" '/orders/' + index">Detail</b-button>

とすると、indexの部分がURLになり、ボタンを押した後に表示されます。
