Missing config values in ProductModifier constructor results in a fatal error

[awebber-chl]

For some reason, certain products in both of my test stores come back missing some config values. I have to cast these three values as bool in order to ensure that null values are interpreted as false.

    public function __construct(?stdClass $optionObject = null)
    {
        if (
            !is_null($optionObject) && !empty($optionObject->config)
            && get_class($optionObject->config) !== ProductModifierConfig::class
        ) {
            error_log('config='.json_encode($optionObject->config));
            $this->config = new ProductModifierConfig(
                (bool)$optionObject->config->product_list_adjusts_inventory,
                (bool)$optionObject->config->product_list_adjusts_pricing,
                (bool)$optionObject->config->product_list_shipping_calc
            );
        }

        if (!is_null($optionObject) && isset($optionObject->config)) {
            unset($optionObject->config);
        }

        if (!is_null($optionObject) && isset($optionObject->option_values)) {
            $this->option_values = array_map(function ($v) {
                return ProductModifierValue::buildFromResponse($v);
            }, $optionObject->option_values);
            unset($optionObject->option_values);
        }

        parent::__construct($optionObject);
    }

Here are a few examples of the configs I get back:

config={"file_types_mode":"specific","file_types_supported":["images"],"file_types_other":[],"file_max_size":524288}
config={"checkbox_label":"","checked_by_default":false}

I can see the issue, I'll get some better test data in there and fix asap.
