Previously I was using GOOGLE_KEY=my_secret_key and the gemini is able to return my answer. Then I try to using Vertex AI yesterday using this configuration is working:

GOOGLE_MODELS=gemini-2.5-pro-preview-06-05,gemini-2.5-flash-preview-05-20,gemini-2.0-flash-001
#GOOGLE_KEY=my_secret_key <-- I'm not using

#GOOGLE_LOC=global <-- disabled

Something went wrong. Here's the specific error message we encountered: { "type": "undefined", "info": "[{ "error": { "code": 404, "message": "Publisher Model `projects/librechat-1749684596838/locations/us-central1/publishers/google/models/gemini-2.5-pro-preview-06-05` not found.", "errors": [ { "message": "Publisher Model `projects/librechat-1749684596838/locations/us-central1/publishers/google/models/gemini-2.5-pro-preview-06-05` not found.", "domain": "global", "reason": "notFound" } ], "status": "NOT_FOUND" } } ]" }

seeing the error i'm just change the locations:
GOOGLE_LOC=global

and it is produce different error:

file on api/data/auth.json is stored

my docker-compose.override.yml

services:
  # USE LIBRECHAT CONFIG FILE
  api:
    command: npm run backend:dev
    environment:
      - NODE_ENV=development
    volumes:
      - type: bind
        source: ./librechat.yaml
        target: /app/librechat.yaml
      - type: bind
        source: ./api/data/auth.json
        target: /app/api/data/auth.json

At this moment, I'm switching back to non Vertex AI configuration following this documentation https://www.librechat.ai/docs/configuration/pre_configured_ai/google#generative-language-api-gemini

For the latest google model, make sure you are on the latest version of LibreChat as there was a small issue with compatibility already resolved here: #7768
