Doesn't append a new value or getting an error in toSearchableArray method

[vezlius]

If I want to load relationship tasks in a parent's model toSearchableArray() method

public function toSearchableArray()
{
    $this->tasks;
    return $this->toArray();
}

I get this error: ErrorException: mb_strtolower() expects parameter 1 to be string, array given

or, if I want to adjust array in the same method...

public function toSearchableArray()
{
    $array = $this->toArray();
    $array['test'] = 'Test string';
    return $array;
}

...it doesn't append new value. It's like nothing ever happened.

Everything works as intended when I try different search driver. Any ideas?

I'm seeing the same thing. toSearchableArray doesn't appear to have any impact on the search results

[khuesmann]

same for me ... toSearchableArray has no impact on search results

edit: i had to use scout:import App\Model instead of tntsearch:import App\Model

I think I have the same issue. I can manually build the index using createIndex(), but updates and edits to the model are ignored.

Here's the full exception

This happens when you reference an eloquent relationship, e.g. if you were indexing a Post that hasOne->(Author), and you're trying return $this->author->name (as an example) within a toSearchableArray().
