Could you guys take a look at the AssertionDLApproach class parameters labelCol and targetCol?

[egenc]

This Java code:

AssertionDLApproach assertionDLApproach = new AssertionDLApproach();
assertionDLApproach.setLabelCol("my_labels");

generates this error (for setLabelCol and setTargetCol):

java.util.NoSuchElementException: Param my_labels does not exist.

make sure you have column my_labels in you dataframe. Solved the issue for me
