ajax request on project 1 call project 2 symfony return Unexpected token <

I have 2 projects, let's call them backend and frontend. Backend is a Symfony3 project and Frontend is a simple html page with javascript in it.

I would like to call a peculiar url of the backend from the frontend so that it would return a string (a url).

So what I tried to do is a simple ajax get request with the backend url I would like to request but this returns

SyntaxError: Unexpected token "<"

(for html dataType) and

SyntaxError: Unexpected token.

(for json and jsonp dataType).

I tried with dataType json, jsonp, html adapting each time the controller response to answer respectively json, json, and html.

When I try this request from postman everything works just fine and i get either my json or html.

There is obviously something I don't understand.

Is there anybody that could explain me what I do wrong and how I could do it.

Below is my frontend project ajax request (for html in that case but I've let the commented json part I've jused for test in case of...) 

$.ajax({
                url: 'http://sevignemiroir.local/display',
                type: 'GET',
                dataType:  "html",
                //dataType: "jsonp"
                success: function(response) {
                    console.log('success');
                    console.log(response);
                },
                error: function (response) {
                    console.log('error');
                    console.log(response);
                }
            })

And this my response from my backend symfony controller

public function indexAction()
{
    //return $this->json('toto');
    return $this->render('display/test.html.twig', [
        'toto' => 'toto'
    ]);
}

the test.html.twig file : 

<div>test</div>

I am a bit confused :

These are the questions I'm getting confused with and if anyone would be kind enough to explain it, that would be greatly appreciated!

I don't know if that's important but I'm using MAMP and both project have virtualhosts configured

Many thanks to those that will take time to read this :)

It now works but... I don't know why. I was installing various bundle on symfony (FOSRest, NelmioCors, JMS) and tried a jquery cross-plugin plugins, nohing was working but when I removed al of them, it now worked.. :/
