Why am I getting an error when trying to delete all future events in a calendar?

[Stephanie Saad]

Error(s) occurred.

An error occurred while trying to delete event 20171010T225744Z--76744798@confluence.abc-dev.net.au.

Every time I try to delete future instances of two reoccurring events, I am getting the above error. 

I am able to delete each individual instance of the event, however this will take me forever to do as I originally set up the event as reoccurring with no end dates.

Anyone have any clues?

def sql = new Sql(conn)
def results = sql.rows("select * from tableexample.repdata ")
return results
