[keycloak-user] Development help

[Tomás García]

Hi,

I've developed an API service for Keycloak. It's a bit complex algorithm
where the clientSession needs to be recovered later if something happens,
so I put a note in the style of HMAC + Session ID as Keycloak does in other
places and then next, when the algorithm needs to continue in the following
request to the same endpoint, I recover the session. Inside the API
service, I'm adding users so I have to commit the transaction just in case
a ModelDuplicateException happens, as I've seen in other places of
Keycloak's code.

So I'm receiving this exception when I recover the client session from the
note (note: a user was added and committed previously). I've tried to start
a new transaction after committing, but yet I still get the same exception.

Any help or ideas will be welcome. Thanks.
