LFF502-Unexpected Error - Unknown field multiplicity

asked on November 2, 2022

This is a new error for me. Does anyone know what 'Unknown field multiplicity' is referring to? End users were receiving this when trying to submit a form from a user task yesterday.

An unexpected error has occurred. [LFF502-UnexpectedError]

The "Unknown field multiplicity." error happened when a field outside a collection/table is submitted as a field inside collection/table. For example, for field outside collection/table, the ID of it should like "Field1", but somehow it becomes "Field1(1)" which means the first set/row inside collection/table.

Can you check it is a one time error or you can always reproduce with that user task if you run the process again? If you can always reproduce with that user task, the form used in the user task may be corrupted.

The error happened over and over throughout the day earlier this week, but only on one of our the load balanced servers. The next day it stopped.
