3738659 - Required field validation message displays in non-default language in new candidate experience – Recruiting

When candidates tries to update their application or candidate profile without a required field. The validation error message appears on a different language compared to the one default language selected by the candidate on their candidate profile. 

SAP SuccessFactors Recruiting 

1. Go to the career site.
2. Apply to a job requisition using the redesigned/new candidate experience.
3. In the application form, leave a required field empty.
4. Submit the application.
5. Observe that the validation error message appears in a non-default language instead of English.
6. Alternatively, create a candidate profile, complete fields, save, and observe a required-field message appearing in a non-default language.

The application controller caches the message formatter instance (SFMessages) from the backend. When the first API request after application/instance startup sets a locale, that locale is reused for all subsequent users on that instance. In multi‑instance deployments, different instances may cache different locales, so users receive error messages in different languages depending on which instance handles their request.

The fix regarding the issue will be part of 1H2026 Release. For release & patch timelines, please refer to SAP SuccessFactors Patches Knowledge Base.
