The following has evaluated to null or missing:
==> fields["content"][0].getValue().getString(realLocale)  [in template "20155#20195#CONTENT" at line 14, column 19]

Tip: If the failing expression is known to be 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)??
