FAILED_PRECONDITION (400): User location is not supported for the API use

Google Antigravity
1

Hello,

I would like to report what appears to be an incorrect location classification when using Google Antigravity.

I have reproduced the issue using both:

  • Antigravity IDE (latest version)
  • Antigravity CLI 1.1.1

Environment:

  • Ubuntu 22.04.5 LTS
  • Windows 11
  • Google AI Pro subscription
  • Public IP: 185.112.249.237
  • Public IP location: Slovakia

The issue is fully reproducible.

Authentication succeeds successfully.

The CLI is able to:

  • authenticate my Google account;
  • detect my Google AI Pro subscription;
  • fetch the list of available models.

However, every attempt to execute a prompt fails with:

FAILED_PRECONDITION (code 400):
User location is not supported for the API use.

The same error occurs:

  • in Antigravity IDE on Windows;
  • in Antigravity CLI on Windows;
  • in Antigravity CLI running directly on an Ubuntu VPS.

Because the error is reproduced directly on the VPS (without Windows, VPN client, or local network involvement), this appears to be unrelated to my local machine.

Relevant log excerpt:

OAuth: authenticated successfully as a....@gmail.com

URL:

FAILED_PRECONDITION (code 400):
User location is not supported for the API use.

Could you please check whether my IP address, network, or account has been incorrectly classified as being in an unsupported location?

If additional information (logs, timestamps, request IDs, etc.) is required, I will gladly provide it.

Thank you.
