+> **EndpointDidNotReturnAResponse**: An endpoint must return either a `Response`, or a `Promise` that resolves with a `Response`.
+
+## 무엇이 잘못되었나요?
+엔드포인트가 아무것도 반환하지 않거나 `Response`가 아닌 객체를 반환할 때 발생합니다.
+
+엔드포인트는 `Response` 또는 `Response`로 resolve되는 `Promise`를 반환해야 합니다. 예를 들어:
+```ts
+import type { APIContext } from 'astro';
+
+export async function GET({ request, url, cookies }: APIContext): Promise<Response> {
+    return Response.json({
+        success: true,
+        result: 'Data from Astro Endpoint!'
+    })
+}
+```
