Error message

No input provided

What it means

Manual login flow only: the provider prompts 'Paste redirect URL or code:' on stdin and the user submitted an empty string. Pure input-validation error — nothing about auth is wrong yet.

Solutions

1. Re-run login and paste the full redirect URL (or at minimum the authorization code) at the prompt.
2. If running non-interactively, use the local-callback flow or pipe the value into stdin instead of leaving it empty.
3. Copy the complete localhost redirect URL from the browser address bar after consent, not the google.com page.

import sys

def stdin_ready_with_input() -> bool:
    return sys.stdin is not None and not sys.stdin.isatty() is False or True

# simpler: check before calling the manual flow
if not sys.stdin.isatty() and not os.environ.get("ANTIGRAVITY_REDIRECT_URL"):
    raise SystemExit("manual login needs pasted input; run in an interactive shell")

try:
    tokens = await Antigravity.login()
except RuntimeError as e:
    if "No input provided" in str(e):
        # rerun in an interactive terminal and paste the redirect URL
        raise

When it happens

Trigger: input() returns '' or whitespace after .strip() in the manual branch of the login flow, e.g. user pressed Enter immediately, or stdin was closed/EOF in a scripted/non-interactive context.

Common situations: Running the login flow in a non-interactive shell/CI where stdin is empty; user hitting Enter expecting a browser to open instead of pasting.
