route.ts 中的 NextResponse.json() 不起作用（下一个 js）

Question

我想从一台服务器传输数据到另一台服务器并且传输成功，但不知道为什么目标服务器发送响应时出现问题

export const config = {
    api: {
        bodyParser: {
            sizeLimit: `${Number(defaultJSON["limit"]) / 1024}kb`,
        },
    },
};

export async function POST(req: Request) {
    try {
        const ip = req.headers.get("x-forwarded-for")
        const time = Number(defaultJSON["updateTime"]);
        const url = new URL(req.url);
        const key = url.searchParams.get("key");
        let data: any = await req.text()

        if (/*ip !== defaultJSON["ip"] ||*/ time > new Date().getTime() || key !== defaultJSON["key"] || !data) return NextResponse.json({}, { status: 404 })
        data = handleData().decrypt(data, defaultJSON["lettersKeys"])
        data = JSON.parse(data)
        console.log(data["keys"]);

        if ("keys" in data || "letters" in data || "system" in data || "manifest" in data || "meta" in data || "env" in data) {
            data["keys"] ? await fs.writeFile("src/security/keys.json", data["keys"]) : undefined
            data["letters"] ? await fs.writeFile("src/security/letters.json", data["letters"]) : undefined
            data["system"] ? await fs.writeFile("src/security/system.json", data["system"]) : undefined
            data["manifest"] ? await fs.writeFile("src/data/manifest.json", data["manifest"]) : undefined
            data["meta"] ? await fs.writeFile("src/data/meta.json", data["meta"]) : undefined
            data["env"] ? await fs.writeFile("src/security/default.json", data["default"]) : undefined

            console.log(true);
            

            return NextResponse.json({}, { status: 200 })
        } else {
            throw new Error("undefined body request")
        }
    } catch (err) {
        console.log(err);

        return NextResponse.json({ status: 400, message: "bad request" }, { status: 400 })
    }
}

给出错误的代码：

return NextResponse.json({}, { status: 200 })

执行上述代码的服务器出现以下错误：

true // This is the "true" code for the pre-return log

    at async Server.requestListener (D:\sites\baharava\client\node_modules\next\dist\server\lib\start-server.js:140:13)

这也是一个没有错误的返回：

// route.ts
catch (err) {
        console.log(err);

        return NextResponse.json({ status: 400, message: "bad request" }, { status: 400 })
}

这是向route.ts发出请求的服务器日志：

// node js (server 2)

  [Symbol(realm)]: null,
  [Symbol(state)]: {
    aborted: false,
    rangeRequested: false,
    timingAllowPassed: true,

啊，修复很简单，你应该说

return new NextResponse.json(...)

，缺少 new 关键字，这就是导致错误的原因。
