<div>Thank you for the comment!</div>
<div>I’ve checked the behavior and previous version does not indeed cover the case with box.NULL. Suitable fix and tests were added. <br>

<div class="class_1573154769_mailru_css_attribute_postfix">Maria, thanks for your patch!<br>
<br>
But as I see you don't consider the case of box.NULL that has 'cdata' type, but doesn't have<br>
__serialize metamethod.<br>
<br>
It will lead to an error:<br>
```
<p class="p1_mailru_css_attribute_postfix_mailru_css_attribute_postfix"><span class="s1_mailru_css_attribute_postfix_mailru_css_attribute_postfix">- error: '[string "return x:__serialize()"]:1: ''void *'' has no member named ''__serialize'''</span></p>
