Signup in hydrogen and redirect doesnot work

[Pankajmehta1998]

This is my hydrogen code:
`import { Link, useFetcher } from '@remix-run/react';
import { useEffect, useState } from 'react';
export default function Register() {
const { Form, ...fetcher } = useFetcher();
const { data, state } = fetcher;
const [signupData, setSignupData] = useState({
firstName: "",
lastName: "",
Email: "",
Password: ""
});

const handleChange = (e: any) => {
const { name, value } = e.target;
setSignupData({
...signupData,
[name]: value
});
};

return (

CREATE ACCOUNT

      <button className="account-create-button" type="submit" >CREATE</button>
      <Link className="account-return-to-shop" to="/">Return to Store</Link>
      <input type="hidden" name="login_with_shop[analytics_trace_id]" value="1ecd938b-a737-4a58-b7d1-931504945f4a" />
    </form>
  </div>
</div>

)
}this is my component code and import { json, redirect, type ActionArgs } from '@shopify/remix-oxygen';
import { CREATE_ACCOUNT } from '~/graphql/Mutation/Mutation';

export async function action({ context, request }: ActionArgs) {
const { storefront } = context;
const formData = await request.formData();
const firsName = formData.get('firstName') as string;
const lastName = formData.get('lastName') as string;
const email = formData.get('Email') as string;
const password = formData.get('Password') as string;

try {
    const accountCreation = await storefront.mutate(CREATE_ACCOUNT, {
        variables: {
            input: {
                firstName: firsName,
                lastName: lastName,
                email: email,
                password: password,
                acceptsMarketing: true,
            },
        },
    });

    const customerCreate = accountCreation?.customerCreate;
    const userErrors = customerCreate?.customerUserErrors;
    if (userErrors && userErrors?.length > 0) {
        if (userErrors[0]?.message === 'Email has already been taken') {
            return new Response('Email has already been taken', { status: 200 });
        } else {
            return new Response(`Error: ${userErrors[0]?.message}`, { status: 400 });
        }
    }

    const customer = customerCreate?.customer;

    if (customer && customer?.acceptsMarketing) {
        return new Response(`We have sent an email to ${email}, please click the link included to verify your email address.`, { status: 200 });
    } else {
        return new Response('Account Creation failed', { status: 400 });
    }
} catch (error) {
    console.error('Error subscribing to newsletter:', error);
    return new Response('Internal server error', { status: 500 });
}

}
export function loader() {
return redirect('/account/register');
