Description

Hello,

We are using Consul as the service discovery and everything was working fine for apisix v3.8. But after upgrade to v3.9, we got following errors:

2024/04/09 06:07:16 [error] 49#49: *8920 [lua] init.lua:91: nodes(): fetch nodes failed by , return default service, client: 10.0.2.59, server: _, request: "GET / HTTP/1.1", host: ""
2024/04/09 06:07:16 [error] 49#49: *8920 [lua] init.lua:548: handle_upstream(): failed to set upstream: no valid upstream node: nil, client: 10.0.2.59, server: _, request: "GET / HTTP/1.1", host: "***"

Nothing else is changed except the apisix version. Thanks a lot.
