What the error looks like
Cause
The client application has a newer version than the server.
👉 This causes a version mismatch and the application is unable to properly initialize certain components (event handlers).
Resolution
update ABRA Flexi on the server to the same or a higher version
oruse a client version that is the same as (or older than) the server version
Recommendations
ideally, always keep the client and server on the same version
if you are using a cloud environment, allow the automatic client update to complete
