Subject: Gemini API returning 404 error with “v1beta” reference from modern SDK

Description: I am consistently receiving a 404 error when trying to call the Gemini API. The error message incorrectly references the “v1beta” API version, even though I am using an up-to-date client library. This appears to be a backend routing issue.

  • Project Name: MetaTag

  • Project ID: (PII Removed by Staff)… (You can find this on your Google Cloud dashboard)

  • API Being Used: Gemini API (Generative Language API)

  • Exact Error Message: 404 models/gemini-1.0-pro is not found for API version v1beta, or is not supported for generateContent.

Troubleshooting Steps Already Taken: We have already performed extensive troubleshooting and have confirmed the following:

  • The google-generativeai Python library is fully up-to-date (version 0.8.5).

  • The script is calling the correct model: models/gemini-1.0-pro.

  • The “Gemini API” is enabled in the project.

  • The issue persists even after creating a brand new project and a new, restricted API key.

  • The Google Cloud Status Dashboard shows no active incidents.
