Copy code
"message": "Publisher Model `projects/coldreach/locations/us-central1/publishers/google/models/gemini-3-flash-preview` was not found or your project does not have access to it. Please ensure you are using a valid model version. For more information, see: https://cloud.google.com/vertex-ai/generative-ai/docs/learn/model-versions",a
