新建会话失败：app-server 未返回 thread id

Error message

新建会话失败：app-server 未返回 thread id

What it means

Raised in mobile_relay_page when a new chat session is created but the app-server response contains no thread id, so the client cannot track the new session. Indicates an unexpected or protocol-mismatched app-server reply.
