I got the same error as in the title "oxTrust wasn't allow to access user data" on the UI after successful login.
oxtrust had this log
```
2021-02-24 19:07:45,262 ERROR [qtp1989335500-16] [org.gluu.oxtrust.action.Authenticator] (Authenticator.java:316) - Failed to get id_token
```
But when we change url from error and hit /identity url, it successfully got into application.
I am using "gluufederation/oxtrust:4.2.2_04" image for oxtrust.
