Why does a 403 error occur during authorization?

Question

Node.js

Expected behaviour. By clicking on register, we get a token, save it in localStorage (it works), immediately the second request to read data from a closed route on the server, present the token (403).
Through Postman it works without errors.

Answer 1

try it like this

axios({
      method: 'post',
      url: `${ROOT_URL}/posts`,
      data: {
      },
      headers: { authorization: localStorage.getItem("token") }
    })
