PHP Warning: assert(): No status key could be found for ReviewAssignment on 605 failed

Hi,
Here is another php warning which is appearing quite frequently;

[17-Oct-2020 15:04:05 America/New_York] PHP Warning:  assert(): No status key could be found for ReviewAssignment on 605 failed in /home/seisense/journal.seisense.com/lib/pkp/classes/submission/reviewAssignment/ReviewAssignment.inc.php on line 605

How to rule this out, where is the problem?
Looking for your help
