amazon-web-services - API を提供するために aws-sam-local を取得しようとしています

Question

私は簡単なプロジェクトを持っています。基本設定はこんな感じ…

project
 |- etc
 |   |- sam.yaml
 |   \- swagger.yaml
 |- src
 |   |- client
 |   |   \- Client files (VUE frontend)
 |   \- backend
 |       |- index.js
 |       \- package.json
 \- gulpfile.js

gulp を実行すると、buildフォルダーが作成されます。なんかこんな感じ…

build
 |- client
 |   |- index.html
 |   \- More static client files
 |- backend
 |   |- index.js
 |   |- package.json
 |   \_ node_modules
 |       \- Lots of stuff
 \- backend.zip

ビルドはうまく機能します。変更を加えるたびに ZIP をラムダにアップロードし、クライアント ディレクトリを S3 にアップロードするのではなく、ローカルで実行したいと考えています。

これを行うには、aws-sam-localを実行しています。はい、dockerインストールして実行しています。プロジェクトフォルダーからこれを実行します...

sam local start-api -t etc/sam.yaml -s ../build/client/

これで、ブラウザーにアクセスしてhttp://localhost:3000/にアクセスし、状況を確認できます。予想どおり、私の静的ファイル (index.html) は問題なく読み込まれます。しかし、API ルートhttp://localhost:3000/testにアクセスしようとすると、404 が返されます。

aws-sam-localを取得してラムダ API を実行するにはどうすればよいですか?
