FreeMarker template error!

FreeMarker template error:
The following has evaluated to null or missing:
==> event.dt_surrogate_key  [in template "ComponentTemplateSource:Featured Event:503140" at line 5, column 15]

----
Tip: It's the step after the last dot 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)??
