Anyone know what the below secret is referring to?

level=error msg="[K8s] received secret to process that was older than the last secret operated on. (256559510 vs 256559619)"
 level=error msg="error syncing 'fleet-default/bootstrap-template-d4lsj-machine-plan': handler secret-watch: secret received was too old, requeuing"

I believe that there was a reference to a newer version of the secret on the system when compared to the secret instance it’s comparing to
