[404 Not Found] API Gateway HTTP Protocol Path Matching with stage

We have an HTTP protocol API that has 2 deployment stages: test and prod.
My understanding is the way the package match for a path is through the API Gateway Event `rawPath` property.
When the API has stages the rawPath will look like this `/{stage}/my-path` and will not match with any path.

先重現 test 和 prod 階段的 HTTP API Gateway 事件，並檢查 rawPath 如何用於套件比對。追蹤現有的路徑比對進入點，並新增涵蓋範圍以顯示包含階段的路徑能正確到達 /my-path；完成條件是兩個階段對相符的路由都不再回傳 404。
