[baidu_youth] %s (errno=%d)

Error message

[baidu_youth] %s (errno=%d)

What it means

Catch-all in BaiduYouth.doRequest (drivers/baidu_youth/util.go:113): the endpoint returned JSON with a non-zero errno, and the driver wraps the best available message as '[baidu_youth] %s (errno=%d)'. The message is extracted from the response body (extractBaiduMessage); errno -6 specifically maps to 'cookie expired or invalid' when no message is present.

Solutions

1. For errno=-6, update the BDUSS/SToken cookies in the storage config and re-init
2. Check the numeric errno against Baidu docs and the extracted message for the specific endpoint
3. Verify server clock accuracy (NTP) since several calls sign with current time
4. Retry once after re-init for transient errnos

func isBaiduYouthErrno(err error) (int, bool) {
    var target errnoError
    if errors.As(err, &target) {
        return target.code, true
    }
    // string fallback for the wrapped fmt.Errorf
    var code int
    if n, _ := fmt.Sscanf(err.Error(), "[baidu_youth] %*s (errno=%d)", &code); n == 1 {
        return code, true
    }
    return 0, false
}

body, err := d.get(ctx, path, params, &resp)
if err != nil {
    if code, ok := isBaiduYouthErrno(err); ok && code == -6 {
        // cookie expired: operator must refresh BDUSS/SToken in config
        return fmt.Errorf("baidu_youth cookie expired: update storage credentials: %w", err)
    }
    return err
}

When it happens

Trigger: Any BaiduYouth get/post with failing errno: expired BDUSS/SToken cookie (-6), invalid signature on locatedownload (wrong sk or time), removed file, or rate limiting.

Common situations: Cookie pasted into config has expired (Baidu rotates sessions); server clock skew breaking time-based signatures; file deleted between list and link.
