$FreeMarker template error:
The following has evaluated to null or missing:
==> defenderAiService  [in template "templates/web/components/home/defender-ai-contact-form.ftl" at line 72, column 37]

----
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. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
