FreeMarker template error (HTML_DEBUG mode; use RETHROW in production!)
The following has evaluated to null or missing:
==> lang [in template "WEB-INF/views/portal/home/index.ftl" at line 36, column 7]
----
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)??
