템플렛을 가공하고 있는 동안 과실은 일어났다.
The following has evaluated to null or missing:
==> .vars['reserved-article-display-date']  [in template "20101#20127#122801" at line 1, column 31]

----
Tip: It's the final [] step that caused this error, not those before it.
----
Tip: If the failing expression is known to legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
