Error message

api error

What it means

Generic Error thrown inside doGot when the response body is a string (i.e. an HTML challenge page, not the expected JSON) but the regex /document\.cookie\s*=\s*"([^"]*)"/ finds no match. It means the server returned an HTML page whose cookie-setting syntax the helper cannot parse, so it cannot proceed with the challenge.

Solutions

1. Fetch the same URL with curl/the helper's cookieJar and inspect the HTML to see how the cookie is now set; update the regex accordingly.
2. If the page is a captcha/hard block, the IP is likely banned — route through a different egress or retry later.
3. Confirm the endpoint URL (_link in mv.ts/tlist.ts) still returns the challenge and not a 404.

Example fix

// before
if (!match) {
    throw new Error('api error');
}
// after (include a snippet for diagnosis)
if (!match) {
    throw new Error(`bt0 api error: HTML challenge has no document.cookie match (first 200 chars: ${data.slice(0, 200)})`);
}

if (typeof data === 'string') {
    const match = data.match(/document\.cookie\s*=\s*"([^"]*)"/);
    if (!match) throw new Error(`bt0 api error: no document.cookie match in HTML (len ${data.length})`);
    cookieJar.setCookieSync(match[1], host);
    return doGot(num + 1, host, link);
}

const isCookieChallengeHtml = (s: string): boolean =>
    /document\.cookie\s*=\s*"[^"]*"/.test(s);

// If the regex misses once, retry the raw fetch — the challenge page can be intermittent:
let body = await got.get(link, { cookieJar });
if (typeof body.data === 'string' && !isCookieChallengeHtml(body.data)) {
    // one fresh attempt before failing
    body = await got.get(link, { cookieJar });
}

When it happens

Trigger: response.data is a string (HTML) but contains no `document.cookie="..."` assignment — e.g. the anti-bot page changed to set cookies via a function call, a meta tag, or no cookie at all (a hard block / maintenance page).

Common situations: bt0 updated its anti-bot template; the page is a hard 403/captcha instead of a JS cookie challenge; an intermediate proxy rewrote the HTML.
