[susu] 按钮URL为空

Error message

[susu] 按钮URL为空

What it means

Empty-response guard: the susu button-detail API returned a decodable JSON payload whose Button.URL field is empty. The endpoint is up but declined to hand out a link for this post_id/index/i (expired, invalid, or not-yet-generated token).

Solutions

1. Treat as a permanent per-button failure: skip this link, don't retry immediately
2. Refresh the parent post/page to obtain fresh button indices
3. Check for account/session requirements on the endpoint
