We are facing an intermittent issue, OakState conflict, upon user login through SAML. On debugging logs, we found below observations,

1. The conflict is of type changeChangedProperty on the property samlResponse at the user node

2. At the same time when the OakState conflict occurs we observe another error which says "Response already committed"

20.10.2020 13:28:46.014 *ERROR* [qtp949652837-104425] org.apache.sling.auth.core.impl.SlingAuthenticator doLogin: Cannot login: Response already committed

Nowhere in our code, we make changes to samlResponse property. Any ideas on how to resolve this conflict?

org.apache.jackrabbit.oak.plugins.commit.ConflictValidator Commit failed due to unresolved conflicts in /home/users/x/<node-name>= {changeChangedProperty = {samlResponse = {{258c5b1b1...,{e852c101e...}}}

Below is the error trace:
