+> **EndpointDidNotReturnAResponse**: 一个端点必须返回一个 `Response`，或者一个解析为 `Response` 的 `Promise`。
+
+## 哪里出了问题？
+当一个端点没有返回任何内容，或者返回的不是 `Response` 对象时会抛出此错误。
+
+一个端点必须返回一个 `Response`，或者一个解析为 `Response` 的 `Promise`。例如：
+```ts
+import type { APIContext } from 'astro';
+
+export async function GET({ request, url, cookies }: APIContext): Promise<Response> {
+    return Response.json({
+        success: true,
+        result: '来自 Astro 端点的数据！'
+    })
+}
