Error message

message ?? code

What it means

Thrown by the bilibili favorites (fav) route when the fav/resource/list API returns a non-zero code. The message is the API's own message (preferred) or the numeric code, propagated verbatim. The request already attached config.bilibili.cookies[uid], so a non-zero code usually means auth or visibility problems.

Solutions

1. Inspect the propagated code: -101 means the cookie for uid is invalid/missing (set config.bilibili.cookies[uid]); -403 means the folder is private.
2. Confirm fid is a public favorites folder owned by uid.
3. Re-copy the cookie from a logged-in bilibili.com session and restart RSSHub.

Example fix

// before
const { data, code, message } = response.data;
if (code) {
    throw new Error(message ?? code);
}

// after
if (code) {
    if (code === -101) {
        throw new ConfigNotFoundError(`bilibili cookie for uid ${uid} is missing or expired (code -101).`);
    }
    throw new Error(`bilibili fav API error for uid ${uid} fid ${fid}: ${message ?? code}`);
}

const { code, message } = response.data ?? {};
if (code) {
    throw new Error(message ?? String(code));
}

function isBilibiliErrorEnvelope(r: any): boolean {
    return r && typeof r.code === 'number' && r.code !== 0;
}

try {
    const { data, code, message } = response.data;
    if (code) throw new Error(message ?? code);
} catch (e) {
    if (/^-101|-403/.test(String((e as Error).message))) {
        // cookie expired or folder private — surface to operator
    }
    throw e;
}

When it happens

Trigger: Requesting /bilibili/fav/:uid/:fid and the API returns code != 0: the fav list is private, the cookie for uid is missing/expired, or fid does not belong to uid.

Common situations: config.bilibili.cookies[uid] unset or expired; target favorited folder set to private; fid typo or a folder that was deleted.
