Ocassionally getting exception

I’m using Keycloak Spring Security Adapter, version 9.0.3.
There is a method there org.keycloak.adapters.springsecurity.token.SpringSecurityTokenStore#saveAccountInfo that ocasionally throws exeption like this:
Went to save Keycloak account %s, but already have %s.
I have no idea what causes that exception - I’ve tried many different things to make it happen but I couldn’t. Users of our application are getting it quite regularly and that annoys them.
Can you help me with that? I would like to know what may cause it, how to defend against it, can I safely override the code that throws it? Any kind of help would be much appreciated.

Thank you in advance.


having the same problem with our application but no response from keycloak as usual. This is a mess
