Getting the following Error "http://localhost:3000/api/signup 500 (Internal Server Error)" on Sign Up feature trying to build in Next React TypeScript

Can anyone tell me why I am getting this error:

Here is my Sign Up front end code

`"use client";

import { zodResolver } from "@hookform/resolvers/zod";
import React from "react";
import { useForm, type FieldValues } from "react-hook-form";
import { signUpSchema, TSignUpSchema } from "@/lib/types";
import Link from "next/link";
import { useRouter } from "next/navigation";

function SignUp() {
const router = useRouter();

const {
register,
handleSubmit,
formState: { errors, isSubmitting, isLoading },
reset,
setError,

} = useForm\<TSignUpSchema\>({
resolver: zodResolver(signUpSchema),
});

const onSubmit = async (data: TSignUpSchema) =\> {
try {
const response = await fetch("/api/signup", {
method: "POST",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify(data),
});

      if (response.status === 400) {
        setError("email", {
          type: "duplicate email",
          message: "email already exists",
        });
      }
      if (response.status === 200) {
        router.push("/login");
      }
    } catch (err) {
      setError("root", {
        type: "unknown",
        message: "unknown error!!please try again",
      });
    }
    
    console.log(data);`

Here is my Servcer Side Code

import { signUpSchema } from "@/lib/types";
import { NextResponse } from "next/server";

import UserModel from "@/models/User";
import connect from "@/utils/db";
import bcrypt from "bcryptjs";

export async function POST(request: Request) {
  const body = await request.json();

  const { email_raw, password_raw } = body;
  const email = signUpSchema.safeParse(email_raw);
  const password = signUpSchema.safeParse(password_raw);

  await connect();

const existingUser = await UserModel.findOne({ email });

  if (existingUser) {
    return new NextResponse("Email is already in use", { status: 400 });
  }

  if (typeof password !== "string") {
    return new NextResponse("Password must be a string", { status: 400 });
  }
  const hashedPassword = await bcrypt.hash(password, 5);
  const newUser = new UserModel({
    email,
    password: hashedPassword,
  });

  try {
    await newUser.save();
    return new NextResponse("user is registered", { status: 200 });
  } catch (err: any) {
    return new NextResponse(err.message || "Internal Server Error", {
      status: 500,
    });
  }
}

Please help on this error. I expected to reach the login Page. Have got no clue what I am doing wrong. But getting the following error:"http://localhost:3000/api/signup 500 (Internal Server Error)". Kind of new here. Would really appreciate the help.

Answers

It seems like you're encountering a server-side error (500 Internal Server Error) when attempting to sign up a user. Let's analyze your code to identify potential issues:

  1. In your front-end code, you're sending a POST request to /api/signup with the user's email and password.
  2. In your server-side code, you're attempting to handle the POST request to /api/signup.
  3. Inside your server-side code, you're parsing the request body to extract the email and password.
  4. You're using Zod schema validation for the email and password fields.

Based on the error message you provided ("Internal Server Error"), it seems like something is going wrong during the execution of your server-side code. Here are a few potential issues to investigate:

  1. Ensure that your MongoDB connection is successfully established in the connect function. Any errors during the connection establishment could result in an internal server error.
  2. Check if there are any errors during the execution of UserModel.findOne({ email }) or newUser.save(). These operations could fail due to database-related issues or validation errors.
  3. Verify that the bcrypt.hash function is working correctly. Ensure that it's receiving valid input and producing the expected hashed password.

To debug further, you can:

  • Add logging statements throughout your server-side code to see where the error occurs and what values are being used.
  • Check your server logs for any additional error messages or stack traces that could provide more insight into the issue.
  • Test your server-side code with different input values to see if the issue is specific to certain data.
  • Use a tool like Postman or curl to manually send requests to your server-side endpoint and see if you can reproduce the error.

By investigating these areas, you should be able to identify and resolve the cause of the internal server error.
