[susu] 按钮返回无效链接

Error message

[susu] 按钮返回无效链接

What it means

Post-decode guard: the JWT decoded to a string that is not a usable link — url.Parse failed, or the scheme is not http/https. The upstream token is structurally valid but carries a garbage/relative payload.

Solutions

1. Log the decoded string to see the actual payload
2. Skip this result as permanently invalid
3. Consider prepending a base host if payloads are relative paths
