Problems with cookie on vercel

I creating back-end program using Fastify, and deployed it on Vercel and got this problem: Cookie “__vercel_live_token” has been rejected because it is in a cross-site context and its “SameSite” is “Lax” or “Strict”. But i setup cookies in my project like this

import { errorHandler } from '@/middlewares/error-handler';
import Fastify from 'fastify';
import cors from '@fastify/cors'
import cookie from '@fastify/cookie'
import router from '@/router';


const fastify = Fastify({
    logger: true,
});

fastify.register(cors)
fastify.register(cookie, {
    parseOptions: {
        httpOnly: true,
        sameSite: 'none',
        secure: true
    }
})


fastify.setErrorHandler((error, request, reply) => {
    errorHandler(error, request, reply)
})

fastify.register(router, {prefix: '/api'})

try {
    await fastify.listen({ port: 5000 });
    console.log(`Server listening at http://localhost:5000`);
} catch (err) {
    fastify.log.error(err);
    process.exit(1);
}

So why i still get this error?

When you set a cookie using:

parseOptions: {
    httpOnly: true,
    sameSite: 'none',
    secure: true

Then you need to use https://localhost:5000 and not http://localhost:5000.
