Could not extract authorization code

Error message

Could not extract authorization code

What it means

The manually pasted input was treated as a redirect URL, but urlparse/parse_qs found no 'code' query parameter — the URL is the wrong page (for example the consent page itself, or a post-consent landing page without ?code=), or the query string was truncated.

Solutions

1. Copy the complete localhost redirect URL, including the full ?code=...&state=... query string
2. If the browser blocks the localhost redirect, copy the code from the page Google shows ('copy this code') and paste the raw code instead
3. Avoid line-wrapping when pasting; paste as one line

from urllib.parse import urlparse, parse_qs

def extract_code(user_input: str):
    if user_input.startswith("http"):
        return parse_qs(urlparse(user_input).query).get("code", [None])[0]
    return user_input or None

if extract_code(user_input) is None:
    print("that URL has no ?code= param; copy the localhost redirect URL or the raw code")

try:
    tokens = await GeminiCLI.login()
except RuntimeError as e:
    if "Could not extract authorization code" in str(e):
        # re-prompt with clearer instructions (use Google's 'copy code' fallback)
        pass

When it happens

Trigger: User pastes a URL that is not the final localhost redirect: no ?code= param, or the query portion was cut off during copy; parse_qs returns code=None.

Common situations: Copying the address of the Google consent page instead of the resulting redirect; browser shows about:blank or blocks localhost navigation so the real redirect URL is never visible; terminal mangles long URLs.
