Caused by: cn.smallbun.screw.core.exception.ScrewException: freemarker.core.InvalidReferenceException: The following has evaluated to null or missing:
==> description [in template "documentation_word.ftl" at line 20, column 4686]

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)??
