Symfony - JS link doesnt work on my server but works in local

I've just created a website with Symfony on local and it works perfectly on, but now I send the project on my debian server but now my JS doesnt work, when I'm on my website all of my JS doesnt work. I searched on internet but I didnt found the solution.

Here my javascripts block :

        {% block javascripts %}
        <script src="https://cdn.jsdelivr.net/npm/axios/dist/axios.min.js"></script>
        <script type="text/javascript" src="{{ asset('/javascript/mainScript.js')}}"></script>
        <script type="text/javascript" src="{{ asset('/javascript/ckeditor.js')}}"></script>
    {% endblock %}

And here the error on the console :

GET https://mywebsite.fr/javascript/ckeditor.js [HTTP/1.1 404 Not Found 297ms]

****** RESOLVED ******

My folder name was "javascript", I've just rename it to "js" and works ??
