When Viewing Events in Admins Console: Cannot read properties of undefined (reading 'hasOwnProperty')

The message in screenshot below has been appearing periodically in a realm when viewing the ‘Events’.

Subsequently clicking ‘refresh and continue’ – and ‘Clear User Events’ under ‘Realm Settings’ appears to resolve it.

There are no obvious log messages (log level DEBUG).

Have changed the ‘User Events Expiration’ to a number of permutations, 60 days, 1 day, etc.

Would anyone have suggestion on pathway to research further? Thanks.
