Librechat freezes on a blank page when accessed through an IAP Authentication

[jmv-gamned]

Hello the community,

Our Librechat is running on a GKE cluster behind IAP authentication. The IAP token refresh occurs correctly when we access the Librechat home url (we see a session cookie __Host-GCP_IAP_AUTH_TOKEN_XXXXX ).

However, when accessing one of Librechat's sub-pages directly (e.g. /c/new or /login), ajax calls to /api/auth/refresh return a 401 "empty token" error, as GCP blocks the call because the __Host-GCP_IAP_AUTH_TOKEN_XXXXX session cookie is missing. That causes Librechat to freeze and stay on a blank page.

Is this a known problem when running Librechat behind IAP authentication? Is there a way to force a redirect to the homepage on 401 errors ?

I'm stuck and I haven't found anything yet.
