Why does everything stop working when it returns null?

Question

JavaScript

Hello!

$('.md-actuality-date').text(suggestion.data.state.actuality_date);
$('.md-data-management-post').text(suggestion.data.management.post);
$('.md-kpp').text(suggestion.data.kpp);
$('.md-management-name').text(suggestion.data.management.name);

Выводит они информацию сюда получая с сервера:
<p class="md-actuality-date"></p>
<p class="md-data-management-post"></p>
<p class="md-kpp"></p>
<p class="md-management-name"></p>

But as soon as one of them gets nothing. Then the whole script stops working. But if that line which received nothing to comment out. Then the script will work.

Explained like an amateur. How could.

Help solve the problem, so that the script would work even if there is no information from the server.

Sincerely!

Generally strange. It seems like in jQuery this construction works without errors:
But in principle, you can do it more clumsily (if you don’t want to write extra checks):

$('.elem').text('' + suggestion.data.state.actuality_date);
