TypeError: array_values(): Argument #1 ($array) must be of type array, null given in array_values()

Issue with the array null check

Please check the above MR.

Update with more null check

The second patch from #6 introduces

Warning undefined variable $switcher_horizontal_position and $switcher_vertical_position

$float_position = $settings->get('float_position');

Float position will never be an array and will always be a string since you can only select one. Therefore,

if(is_array($float_position)){

Is not necessary and it's introducing the undefined variables as it will never pass this check.

Use the first patch from comment #2 if anything.

I have not been able to reproduce the bug. Might want to add the steps to reproduce.

This worked for me.

// Check if $languages is an array before using array_values()
$languages = $settings->get('languages');
if (is_array($languages)) {
    $languages = array_filter(array_values($languages), function($l) {
        return !empty($l);
    });
} else {
    $languages = [];
}

This worked for me:
