[BUG] Userinfo response does not return multi-language claim values

[prathmeshj12]

Description

Summary:

After registering name (fullName) and gender in multiple languages for a test identity, the /oauth2/userinfo response does not return the value in the language requested via claim_locales / per-claim essential claims. Instead, name falls back to English (with the resolved language literally appended to the value, e.g. "Postman Test User eng"), and the essential given_name claim is missing from the response entirely rather than falling back or erroring.

Actual Result:

Userinfo response does not return multi-language claim values

Userinfo response received:

Steps to Reproduce

1. Ensure the test individual's identity record has multi-language values for fullName and gender, including at least eng and fra, e.g.:
   json
   "gender": [
   {
   "language": "eng",
   "value": "MLE"
   },
   {
   "language": "fra",
   "value": "MLE"
   },
   {
   "language": "ara",
   "value": "MLE"
   },
   {
   "language": "hin",
   "value": "MLE"
   },
   {
   "language": "tam",
   "value": "MLE"
   },
   {
   "language": "kan",
   "value": "MLE"
   }
   ],
   "fullName": [
   {
   "language": "eng",
   "value": "TEST_FULLNAMEeng"
   },
   {
   "language": "fra",
   "value": "TEST_FULLNAMEfra"
   },
   {
   "language": "ara",
   "value": "TEST_FULLNAMEara"
   },
   {
   "language": "hin",
   "value": "TEST_FULLNAMEhin"
   },
   {
   "language": "tam",
   "value": "TEST_FULLNAMEtam"
   },
   {
   "language": "kan",
   "value": "TEST_FULLNAMEkan"
   }
   ],
2. Run the FAPI2.0 flow's Initiate PAR request with:
3. claim_locales: fra
4. claims: [fill in: paste the exact "claims" parameter JSON you sent, e.g. {"userinfo":{"given_name":{"essential":true},"phone_number":{"essential":true},"gender":{"essential":true}}}]
5. Complete Initiate Authorization → Flow meta → Flow execute (start / select acr / enter uin / enter password) → Auth callback → Exchange Code for Token → Exchange Token for Userinfo.
6. Inspect the /oauth2/userinfo response.

Expected Behavior

Userinfo response should return multi-language claim values, name should be returned in the requested locale (fra), e.g. reflecting the fra-tagged fullName value, without any resolved-language marker appended to it.

As per the discussion in the triage call, I recall this was not an issue anymore and was working as expected.

Verified the issue in the esaa-mosipid environment. After adding the claims_locale parameter correctly, the UserInfo response is now being returned in multiple languages, hence closing the bug. - https://openid.net/specs/openid-connect-core-1_0.html
