I was trying to navigate a page from aura components but got error like this

Question

code to get pagereference from parent component:

var pageReference = component.get("v.pageReference");
        console.log('getpropertyDetails pageReference'+JSON.stringify(pageReference));

Answer 1

This is probably because you are trying to access an attribute from an object which is null.

In the getSelectedProperty method object associated with the state attribute is null.
