Cannot get a response from PostgreSQL server - postgresql

Question

I freely admit that I am completely new to next-auth and the documentation for Credentials is understandably very light. I have got the email link process to work perfectly and will be moving users across top this.
Unfortunately, I have a lot of user data that will require credentials to login and, after spending a few days getting nowhere, I just want to get some idea of what I am doing wrong! This is my [...nextauth].js file:
import NextAuth from "next-auth";
import Providers from "next-auth/providers";
import axios from 'axios'
const options = {
providers: [
Providers.Email({
server: {
host: process.env.EMAIL_SERVER_HOST,
port: process.env.EMAIL_SERVER_PORT,
auth: {
user: process.env.EMAIL_SERVER_USER,
pass: process.env.EMAIL_SERVER_PASSWORD
}
},
from: process.env.EMAIL_FROM
}),
Providers.Credentials({
credentials: {
mem_num: { label: "Membership Number", type: "text", placeholder: "12345" },
password: { label: "Password", type: "text" }
},
authorize: async (credentials) => {
console.log("credentials: ", credentials)
try {
const data = {
mem_num: credentials.mem_num,
password: credentials.password
}
const user = await login(data)
if (user) {
console.log('user:', user)
return user
}
} catch (error) {
if (error.response) {
console.log(error.response)
Promise.reject(new Error('Invalid Number and Password combination'))
}
}
}
})
],
site: process.env.NEXTAUTH_URL || "http://localhost:3000",
database: process.env.DATABASE_URL,
session: {
// Use JSON Web Tokens for session instead of database sessions.
// This option can be used with or without a database for users/accounts.
// Note: `jwt` is automatically set to `true` if no database is specified.
jwt: true,
},
}
const login = async data => {
var config = {
headers: {
'Content-Type': "application/json; charset=utf-8",
'corsOrigin': '*',
"Access-Control-Allow-Origin": "*"
}
};
const url = process.env.DATABASE_URL;
const result = await axios.post(url, data, config);
console.log('result', result);
return result;
};
export default (req, res) => NextAuth(req, res, options);
