Javascript NextJS 服务器端获取 TypeError：无法从 http：localhost：3000apitest 解析 URL

我try 在NextJS(dev模式)中从API终结点的另一个资源获取数据，并收到以下错误:

error - TypeError: Failed to parse URL from httр://localhost:3000/api/test

  }
}

以下是我在/src/pages/api/checkout.js中使用的代码:

async function infoAPI() {
  return fetch('httр://localhost:3000/api/test');
}

export default async function handler(req, res) {
  const result = await infoAPI();

  //...

  res.status(200).json({ message: 'success', data: result });
}

httр://localhost:3000/api/test只是一个例子.无论fetch-LOCALHOST或EXTERNAL提供什么URL，错误都是相同的.我需要调用应用程序中的一些外部URL，如下所示.

它能有什么问题呢？

Update:个

http.get('httр://localhost:3000/api/test', (res) => {/*...*/})个请求也存在同样的问题:

    ... 
{
  input: 'httр://localhost:3000/api/test',
  code: 'ERR_INVALID_URL',
  page: '/api/checkout'
}

我在Node v19.4.0(Windows 10)上运行Next v13.2.4.
