I get this error message when I try to test the /api/register end point with Postman:

request: { url: "http://0.0.0.0:8000/api/register", method: "POST", hasBody: true }
response: { status: 404, type: undefined, hasBody: false, writable: true }

```This is my `auth_controller.ts` file:

import {
  create, verify, decode, getNumericDate, RouterContext, hashSync, compareSync
} from "../deps.ts";
import { userCollection } from "../mongo.ts";
import User from "../models/user.ts";

export class AuthController {
  async register(ctx: RouterContext) {
    const { value: { name, email, password } } = await ctx.request.body().value;

    let user = await User.findOne({ email });
    if (user) {
      ctx.response.status = 422;
      ctx.response.body = { message: "Email is already used" };
      return;
    }
    const hashedPassword = hashSync(password);
    user = new User({ name, email, password: hashedPassword });
    await user.save();
    ctx.response.status = 201;
    ctx.response.body = {
      id: user.id,
      name: user.name,
      email: user.email
    };
  }
  async login(ctx: RouterContext) {
    const { value: { email, password } } = await ctx.request.body().value;
    if (!email || !password) {
      ctx.response.status = 422;
      ctx.response.body = { message: "Please provide email and password" };
      return;
    }
    let user = await User.findOne({ email });
    if (!user) {
      ctx.response.status = 422;
      ctx.response.body = { message: "Incorrect email" };
      return;
    }
    if (!compareSync(password, user.password)) {
      ctx.response.status = 422;
      ctx.response.body = { message: "Incorrect password" };
      return;
    }

    const key = await crypto.subtle.generateKey(
      { name: "HMAC", hash: "SHA-512" },
      true,
      ["sign", "verify"],
    );

    const jwt = create( { 
      alg: "HS256",
      typ: "JWT",
    }, {
      iss: user.email,
      exp: getNumericDate(
        Date.now() + parseInt(Deno.env.get("JWT_EXP_DURATION") || "0"))
    },
    key
    );

    ctx.response.body = {
      id: user.id,
      name: user.name,
      email: user.email,
      jwt,
    };
  }
}

export default new AuthController();

What is the problem and how can I resolve it?
