Recently I experienced the same problem. Here is my solution:

public function clone($id)
{
    $this->crud->hasAccessOrFail('clone');
    $this->crud->setOperation('clone');

    $clonedEntry = $this->crud->model->findOrFail($id)->replicate();

    // now resolve the value for unique attribute before save. e.g.
    $slug = Str::slug($clonedEntry->name, '-');
    $count = $this->crud->model->whereRaw("slug RLIKE '^{$slug}(-[0-9]+)?$'")->count();
    $clonedEntry->slug = $count ? "{$slug}-{$count}" : $slug;

    // when you are done, save changes
    return (string) $clonedEntry->push();
}

You didn't specify anything about that "unique" attribute. Feel free to customize the resolver according your needs.
