$this->invoice_search_filters of type array is incompatible with the type Illuminate\Contracts\Support\Arrayable expected by parameter $value of collect().

            $this->invoice_search_filters = [
                'currency_code' => $this->getCurrency(),

It seems like getCurrency() must be provided by classes using this trait. How about adding it as abstract method to this trait?
