ResultType "parentProperty" always results in ResultType of "value"

[pyoor]

When setting the resultType to "parentProperty", the result will throw due to the resultType.toLowercase() and then this switch statement:

Furthermore, even if the case statement is set to lowercase ("parentproperty"), the result will fail due to the object property casing (i.e. "parentProperty").

Fixed now in v4.0.0. Thanks for the report!
