Looping to create date range for fiscal month

Hello, using 4.7.8 here:

I get this error: “ERROR Create Date&Time Range 3:5 Execute failed: Cannot invoke “Object.getClass()” because the return value of “org.knime.time.util.SettingsModelDateTime.getSelectedDateTime()” is null”

I am trying to append a date range for every row in a table that has a Fiscal Month start and end date by using them as variables in a loop going one row at a time.

The end result I am looking to achieve is this:

I can execute only the cross-joiner node and it produces one fiscal month of dates no problem, but when executing the loop it fails with the message above!

Any help is greatly appreciated - thank you!
