Restaurant Finder Demo: Gemini API Quota "0" Error in Europe-West1 (Turkey)

[EnderKaran]

Hi ,

I am trying to run the Restaurant Finder agent sample locally following the instructions in the README. However, I am encountering a persistent RESOURCE_EXHAUSTED error, specifically related to regional quotas, even though I created a fresh API Key from Google AI Studio.

Environment:

• OS: Windows
• Region: Turkey (Europe-West1)
• Model: Tried with default (gemini-2.5-flash) and gemini-1.5-flash.

The Issue: When running uv run . for the agent, the request fails with a 429 status code. The error details indicate that the quota limit value is "0" for this region.

Error Log snippet:

"error": {
    "code": 429,
    "message": "Quota exceeded for quota metric 'Generate Content API requests per minute' ...",
    "status": "RESOURCE_EXHAUSTED",
    "details": [
      {
        "reason": "RATE_LIMIT_EXCEEDED",
        "metadata": {
          "quota_location": "europe-west1",
          "quota_limit_value": "0"
        }
      }
    ]
}

Steps Taken:
Created a new API key via Google AI Studio.
Exported the key in the terminal.
Tried changing the model in agent.py to gemini-1.5-flash, but the issue persists with the same "quota_limit_value: 0" error.
