UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 4)

    axios({
      url: url,
      responseType: 'json'
    }).then(data => res.json(data.data.currently)).catch(error => { throw error})
  })

app.listen(3000, () => {
    console.log("Server has started")
})

和我的 JavaScript

  fetch('/weather', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'Accept': …
