I am trying to make a request in axios. The same request works in postman.

await axios({
      method: "post",
      url: `https://ecommersappbytim.herokuapp.com/info/${userId}/update-user`,
      header: {
        "Content-Type": "application/json",
        "auth-token": { token },
      },
      data: {
        firstName: userInfo.fName,
        lastName: userInfo.lName,
        email: userInfo.email,
        password: userInfo.password,
      },
    })

Is there something I am missing? I have made sure that I am passing in the correct data.
