Undocumented requirement on Laravel 9.x

[peters-cmc]

Running legacy Laravel v8 application, Filament v2, Laravel Auditing v13; This plugin can be installed and configured correctly, and displays the Audit tab for the resource, however selecting the tab throws an exception.

Method Illuminate\Support\Arr::map does not exist.

From the Laravel documentation Arr::map was not introduced until Laravel 9 (https://laravel.com/docs/9.x/helpers#method-array-map).

AuditsRelationManager.php references this method:

protected static function extraColumns()
    {
        return Arr::map(config('filament-auditing.audits_extend'), function ($buildParameters, $columnName) {
            return collect($buildParameters)->pipeThrough([
            // etc

Auditing v13 looks to support Laravel v7 onwards.

FWIW I've solved this temporarily by using macros to backport the Arr::map behaviour into this application while I assess our auditing behaviour.

// @see https://github.com/laravel/framework/blob/dc2e925b2d75fc2673a5919c7ad727d68059c08e/src/Illuminate/Collections/Arr.php#L555
Arr::macro('map', function (array $array, callable $callback) {
    $keys = array_keys($array);

    try {
        $items = array_map($callback, $array, $keys);
    } catch (ArgumentCountError) {
        $items = array_map($callback, $array);
    }

    return array_combine($keys, $items);
});
