Populating options of a multiselect does not work?

[vv-ac]

Hi all,

I am trying to populate options for a MultiSelect in Laravel Nova (4.~) using the following code:

            MultiSelect::make('Rights')
                ->options(function() {
                    $rights = \App\Models\Right::all();

                    $options = [];

                    foreach($rights as $right) {
                        $options[$right->id] = $right->name;
                    }

                    return $options;
                })
                ->displayUsingLabels(),

When trying it, Nova returns me "Array to string conversion" and "There was a problem submitting the form". Any ideas on how to solve it? I try to have all $right-name (s) in the options array as I do not know how to do it differently.

Only using a predefined options array is not working for several of my use cases, I would like to give users the possibility to define the options based on another resource to then attach/ detach them to other models.

Thank you!
