Hi,

we are running stress tests with multiple threads using Cosbench

sample workstage(xml):
sample.txt

And i encounter the below mentioned issue -

Tip: If the failing expression is known to be legally null/missing, either specify a default value with 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 parenthessis: (myOptionVar.foo)!myDefault, (myOptionVar.foo)??

The failing instruction (FTL stack trace):

==> ${resource} [in template "404.ftl" at line 14, column 62]
