Hi

I would like to check if nested dict value is defined, eg.:  
when: ansible\_local.resolver.resolver\_override is not defined

But if ansible\_local (fact.d) is not exists I get error message:  
error while evaluating conditional: ansible\_local.resolver.resolver\_override is not defined

Is there any way to create condition if nested dict value is defined regardless of existence the whole dict hierarchy?
