Antigravity managed agent sdk

,

Antigravity Managed agents on the Gemini API are not working - it always shows as soon as it launched:

Sandbox provisioning in progress (attempt 1/5). Retrying in 30s…

Like this till the 5th attempt times out.

What is the fix for this issue?

Can you share the prompt and environment you used?

I figured out the problem, I did not use GEMINI_API_KEY, which was the main issue.

In my GCP org, Vertex AI API Key creation is disallowed. But I tested it through API Key from AI Studio. It worked, thanks.
