Hello, I'm trying to set up the Node backend portion of supertokens - without React. How can I try to login via curl/postman? I'm unclear on the json structure of the POST request. When I try to login via the

auth/signup

route, I always get

{"message": "formFields must be an array"}

I tried something along these lines:

sh
curl -H "Accept: application/json" -X POST -d \{"formFields":"{"id": "email@email.com", "password": "12334"}}" http://localhost:7000/auth/signup -s -S -v -H "Content-Type: application/json"

I also tried other versions, but I can't wrap my head around how to send the POST data via json in the correct format. Relevant node.js server `index.ts`:

js
/**
 * Required External Modules
 */
import express from "express";
import cors from "cors";
import helmet from "helmet";
import supertokens from "supertokens-node";
import EmailPassword from "supertokens-node/recipe/emailpassword";
import Session from "supertokens-node/recipe/session";
import { API_DOMAIN, NODE_PORT, CONNECTION_URI, WEBSITE_DOMAIN } from "./env";

/**
 * App Variables
 */
if (!NODE_PORT) {
  process.exit(1);
}

const PORT = Number(NODE_PORT);

const app = express();

/**
 *  App Configuration
 */
supertokens.init({
  supertokens: {
    connectionURI: CONNECTION_URI,
  },
  appInfo: {
    appName: "Bookclub User Service",
    apiDomain: API_DOMAIN,
    websiteDomain: WEBSITE_DOMAIN,
  },
  recipeList: [EmailPassword.init(), Session.init()],
});

app.use(
  cors({
    origin: WEBSITE_DOMAIN,
    allowedHeaders: ["content-type", ...supertokens.getAllCORSHeaders()],
    methods: ["GET", "PUT", "POST", "DELETE"],
    credentials: true,
  })
);
app.use(
  helmet({
    contentSecurityPolicy: false,
  })
);
app.use(supertokens.middleware());
app.use(supertokens.errorHandler());

/**
 * Server Activation
 */
app.listen(PORT, () => {
  console.log(`Listening on port ${PORT}`);
});

Thank you.
