The ThoughtSpot server returns a field use_browser_language in the User JSON response, but this field is not defined in the User model's allowed properties set. This causes User.validateJsonElement() to throw an IllegalArgumentException, breaking all user-related API calls. The field use_browser_language is: ❌ Not defined in the Java SDK User model (docs/User.md) ❌ Not documented in the REST API v2 Playground ✅ Present in the actual server response SDK Version Tested on both 2.20.0 and 2.21.0 — field is missing in both. // build.gradle.kts implementation("com.thoughtspot:rest-api-sdk:2.20.0") I have raised a issue here - https://github.com/thoughtspot/rest-api-sdk/issues/371

hey @jarvis could you share what release version of Thoughtspot are you on?
