Description

When mixing a Fastify route and an Express route with a wildcard (*), the handler for the Express wildcard route will always be called over the handler for the Fastify route, even if the Fastify route is configured first.

Steps to Reproduce

const Fastify = require('fastify')
const express = require('express')
const router = express.Router()

async function build () {
    const fastify = Fastify()
    fastify.get('/hello-fastify', function (request, reply) {
        reply.send({
            hello: 'fastify'
        })
    })
    await fastify.register(require('@fastify/express'))
    router.get('/hello-express', (req, res) => {
        res.status(201)
        res.json({ hello: 'express' })
    })
    router.get('*', (req, res) => {
        res.status(404)
        res.json({ msg: 'not found'})
    })
    fastify.use(router);
    return fastify
}

build()
    .then(fastify => fastify.listen({ port: 3000 }))
    .catch(console.log)

curl -X GET http://localhost:3000/hello-express    
{"hello":"express"}
curl -X GET http://localhost:3000/hello-fastify   
{"msg":"not found"}

Expected Behavior

When sending a GET request to the /hello-fastify endpoint

curl -X GET http://localhost:3000/hello-fastify  

the handler function provided when calling fastify.get('/hello-fastify, handler function() {...}) should be called and the response should be

{ hello: 'fastify' }

.

Thanks for trying to help @UNES97, but the updated code you posted is (apart from the added comments) the same as the code I originally posted. Also, I'm already registering the express middleware after defining all fastify routes in the code I posted in my initial post.
