How resolve error request between two microservice nodejs and traefik like reverse-proxy

The service 2 exposes /service1/users/:id in this exposure I make a subquery to service1 with axios /service1/users/:id and I go through traefik.

But I get an error 500. The service1 does not receive the request.

Server2

app.get("/server2/users/:id", function(req, res) {
  
  axios.get("http://server_1.localhost/server1/users/2").then( (response) => {
    
    res.json(response);
  })

});

app.listen(3002);

Mon server 1

app.get("/server1/users/:id", function(req, res) {
  
  res.send({
    name: "test",
    lastName: "test",
    rule: "User",
  });
});

I used docker so this my docker-compose file. But I get an error 500. The service1 does not receive the request. But I get an error 500. The service1 does not receive the request.
