data automation test error message

[Pasa]

I'm getting this message when I test automation

Failed: Error: Perform DataAction 'Update/Antal Fl.' failed because Row having key '8cb2cd58' in table 'Track' in field '_RowNumber' is required to have a value.

what does it mean and how can I solve this

Try removing the 'Required?' constraint on the _RowNumber column.
