$ToastMessage is of type SilverStripe\View\ArrayData, thus it always evaluated to true.

            $Body = addslashes($ToastMessage->Message);

It seems like $ToastMessage->Message can also be of type null; however, parameter $string of addslashes() does only seem to accept string, maybe add an additional type check?

            $autohide = $ToastMessage->Type == ValidationResult::TYPE_GOOD ? "true" : "false";

toaster({
    body: '{$Body}',
    className: 'border-0 bg-{$ToastMessage->ThemeColor} text-white',
    autohide: {$autohide}
});
