我有一个 NodeJS 后端我正在开发与 ReactJS 前端一起工作，但我不断收到 500 错误

Question

I am testing my NodeJS backend using Insomnia and while it does work no problem in Insomnia I am getting a 500 error on the frontend every time. I was wondering if anyone maybe knew where this could be coming from if like I said it works just fine on my the endpoint testing program. Since it is a 500 error it is not very descriptive. Links can be shared if needed

const handleSubmit = e => {
e.preventDefault();
console.log("cred username", creds.username);
axios
  .post("https://exampleapi/api/login")
  .then(res => {
    console.log(res.data);
    localStorage.setItem("token", res.data.access_token);
    props.history.push("/");
  })
  .catch(err => console.log(err.response)); };

Answer 1

So I figured it out it was an error in my post request would should have been included was

  const handleSubmit = e => {
e.preventDefault();
console.log("cred username", creds.username);
axios
  .post("https://mystery-doggo.herokuapp.com/api/login", creds)
  .then(res => {
    console.log(res.data);
    localStorage.setItem("token", res.data.payload);
    props.history.push("/");
  })
  .catch(err => console.log(err.response));

};

"creds" after the link and change res.data.access_token to res.data.payload
