Mark Payne commented on NIFI-6776:
----------------------------------

[~dust2sleep] the property is not defined because there's no property named 
"JSON Paths". Rather, the user must click the "+" icon in the top-right corner 
there to add 1 or more user-defined property. The name of the property will 
become the name of the field in the Record that is created, while the value of 
the property must be a valid JSONPath Expression to evaluate against the 
incoming JSON. This is a common pattern, where the user must add 1 or more 
properties to properly configure the component.

> JSONPathReader do not have "JSON Paths" property as default ,but it's  a 
> required property
