Getting an error when I register a user using GraphQL

Question

I'm new to graphQL and was recently told to learn it. I'm trying to do a post request by registering an account but I get an error saying I need a subfield.

const getLoggedInUser = async req => {
  const token = req.headers["x-token"];
  if (token) {
    try {
      return await jwt.verify(token, process.env.JWT_SECRET);
    } catch (e) {
      throw new AuthenticationError(AUTHORISATION_MESSAGES.SESSION_EXPIRED);
    }
  }
};

When you do the mutation, you must also request the payload. This payload is what the error recognizes you as "subfields".

In your case, i see that AccessToken has two subfields, token and user.

You must do the mutation in this way.

mutation {
  registerUser (
  firstName: "test",
  lastName: "test",
  password: "test",
  emailAddress: "test@gmail.com",
  type: "Patient"
  ) {
    token
    user
  }
}
