Hi all,
i am using the dmn engine to compare dates. The engine receives the datetime in the following format (OffsetDateTime in Java): 2023-06-28T12:30:41.432Z
From the error message, it seems that the variable event.eventTransfer.bookingDate returns already a date. But the date and time() function expects a string.
So, if the variable is already a date-time value, you can remove the date and time() function invocation in the input expression.
