SEVERE: Error executing FreeMarker template
FreeMarker template error:
The following has evaluated to null or missing:
==> report.systemInfoMap[info] [in template "Extent.ftl" at line 193, column 95]

---

Tip: It's the final [] step that caused this error, not those before it.

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)??
