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).
Solution
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
Recommendation
ideally, always keep the client and server on the same version
if you are using the cloud version, allow the automatic client update to complete
