@tzssangglass uses the method of "when the route is configured with an upstream_id, the upstream_id is passed into the server_list" to solve it.
Thank you very much @tzssangglass .

I think we can create a temporary variable to cache the upstream_id configured in the plug-in, and delete it after the end of use, so as to avoid the modification of ctx.matched_route.value.upstream_id. For example, create a temporary variable upstream_id_tmp: ctx.matched_route.value.upstream_id_tmp
