antigravity userinfo: response missing email

Error message

antigravity userinfo: response missing email

What it means

Userinfo responded 2xx with decodable JSON, but the email field was absent or whitespace-only. The account may not have an email exposed to this OAuth client (scope not granted), or the response schema put the address under a different key.

Solutions

1. Add the email scope to the Antigravity authorization request and re-authorize
2. Inspect the decoded userinfo JSON for where the address actually appears (e.g. emails array) and map accordingly
3. Fall back to another identifier if email is unavailable for that account type

if strings.Contains(err.Error(), "response missing email") {
	// re-authorize with email scope or use an alternate account identifier
}

When it happens

Trigger: Authorization request lacked the email scope, so Google omits the email field; Workspace accounts with hidden emails; schema change renaming the field.

Common situations: Authorization URL built without email scope; consent screen skipping email grant; service-account-style flows that have no primary email.
