PAIS UI Displays Blank Page Due to Unsupported Browser Language

Products

• VCF Private AI Services

Issue/Introduction

Navigating to the Private AI Services (PAIS) UI may result in a blank page.
The following symptoms will be observed  :

• All pais pods are reporting as running and healthy.
• The PaisConfiguration CRD status indicates Ready is True.
• pais-ingress logs show no errors suggesting a failure in response.
• The browser developer console displays the error: You’re using an inline loader but didn’t provide a loader for PaisUi/ko.

Environment

Private AI Services 2.1.2

Cause

The PAIS UI fails to render when it detects an unsupported browser language setting (e.g., 'ko' for Korean). This occurs because the Transloco i18n library does not successfully trigger a fallback to a supported default language.

Resolution

Broadcom engineering is currently working on a fix for this issue.

Workaround:
To resolve this behavior and access the UI successfully, configure your browser settings to use a supported language.

The supported languages are English, French, Japanese, and Spanish (EN, FR, JA, ES).
