Access token is not valid

Error message

Access token is not valid

What it means

In OpenaiChat.create_async_generator, the authenticated/media path requires an API key (access token) from auth_result; _set_api_key() validates it. If it returns falsy (no api_key present or rejected), MissingAuthError 'Access token is not valid' is raised before any backend call. Note this fires on the needs-auth or media-upload branch only.

Solutions

1. Re-authenticate: run the nodriver login flow (yield RequestLogin -> nodriver_auth) or supply a fresh .har capture so auth_result.api_key is populated
2. Update g4f — token acquisition/refresh logic changes often for this provider
3. If media triggered the auth branch unintentionally, remove media to use the anonymous path (cls._api_key is None branch)
4. Delete stale credential cache so it is re-acquired rather than reused

Example fix

// before
resp = await client.chat.completions.create(model=..., messages=msgs, media=[img])  # MissingAuthError

// after
# perform the interactive login once (nodriver opens a browser) OR update the HAR
resp = await client.chat.completions.create(model=..., messages=msgs)  # anon path, no media

auth = await OpenaiChat.nodriver_auth(proxy)  # or load fresh HAR
if not getattr(auth, 'api_key', None):
    raise SystemExit('OpenaiChat: no access token — run login before requests with media')

def has_valid_api_key(auth_result) -> bool:
    return bool(getattr(auth_result, 'api_key', None))

from g4f.errors import MissingAuthError
try:
    resp = await client.chat.completions.create(model=..., messages=msgs, media=[img])
except MissingAuthError as e:
    if 'Access token' in str(e):
        await OpenaiChat.nodriver_auth(proxy)  # one re-login attempt
        resp = await client.chat.completions.create(model=..., messages=msgs, media=[img])
    else:
        raise

When it happens

Trigger: Requests with media attachments or where cls.needs_auth is true, but auth_result carries no usable api_key — e.g. no HAR file, no nodriver login performed, or an expired access token that _set_api_key refuses.

Common situations: First use without login; access token expired (OpenAI tokens rotate quickly); cached credentials invalidated server-side; using the anonymous branch with media (media forces the auth branch).
