antigravity userinfo: execute request: %w

Error message

antigravity userinfo: execute request: %w

What it means

The GET to the userinfo endpoint failed at the transport level (httpClient.Do). The wrapped *url.Error identifies the real cause: DNS failure, connection refused, TLS error, timeout, or context cancellation after the request started.

Solutions

1. Unwrap the error to distinguish DNS/TLS/timeout and test reachability with curl from the same host
2. Trust the proxy CA or configure the proxy on the http.Client
3. Retry — userinfo is a read-only idempotent call, unlike the one-shot code exchange

var netErr net.Error
if errors.As(err, &netErr) && netErr.Timeout() {
	// idempotent read — safe to retry with backoff
}

When it happens

Trigger: No egress to the Google userinfo host; TLS interception with untrusted CA; context deadline exceeded mid-request; proxy blocking the endpoint.

Common situations: Sandboxed/CI environments without network; corporate MITM proxies; transient drops during the auth sequence.
