Im getting internal server error 500. unfortunately there is no logs to see what causes it.

here is my ajax calling it :

 createRide(event) {
    console.log(event);
    event.preventDefault();
    event.stopPropagation();
    console.log('Hello', $("#form-create-ride").serialize());
    $.ajax({
        url: '/admin/dispatcher',
        dataType: 'json',
        headers: {'X-CSRF-TOKEN': window.Laravel.csrfToken },
        type: 'POST',
        data: $("#form-create-ride").serialize(),
        success: function(data) {
            console.log('Accept', data);
            this.props.completed(data);
        }.bind(this)
    });
}

this is from : dispatcher-admin.js:455 (see error in console below).

here is the error :
