Cannot read property 'body' of undefined

Hi, I'm having trouble with angular 1.6 integration with the error in title. My usage is nothing special:

 <input type="text" class="form-control" placeholder="comment" ui-tinymce="tinymceOptions"
                               ng-model="model.description">

I use a Service for share tinyMceOptions in various Controllers Controller

...
 $scope.tinymceOptions = tinyMceOptions; 
....

Service

app.service('tinyMceOptions', ['ListProvider',function (ListProvider) {
    return {
        menubar:false,
        plugins: [
            'advlist autolink lists link image charmap print preview anchor',
            'searchreplace visualblocks code fullscreen',
            'insertdatetime media table contextmenu paste code','paste','autoresize','autolink',
            'mention'
        ],
        toolbar: 'undo redo | | bold italic | alignleft aligncenter alignright alignjustify | bullist numlist | link',
        valid_elements : "a[href|target=_blank],strong/b,div[align],br,li,ol,ul,i,em,p,span[id=autocomplete]",
        fix_list_elements : true,
        autoresize_bottom_margin: 4,
        content_css: [
            '/css/tinymce.css'
        ],
        mentions: {
            delimiter: ['@', '#'],
            source: function (query, process, delimiter) {
                // When using multiple delimiters you can alter the query depending on the delimiter used
                if (delimiter === '@') {
                    //TODO angular better integration (insert function)
                   ListProvider.getList(null,null,'ecli')
                       .then(function(data) {
                           process(data);
                        });
                }
                if (delimiter === '#') {
                    ListProvider.getList(null,null,'fundamentalRights')
                        .then(function(data) {
                            process(data);
                        });
                }
            },
            renderDropdown: function() {
                return '<ul class="rte-autocomplete tinymce-autocomplete dropdown-menu"></ul>';
            }
        }};

    }]);
