bug: upstream.upstreams() returns nil

[ali-mahdavi-mehr]

Current Behavior

When we update the upstreams in the dashboard, this value becomes nil.
local upstreams, _ = upstream.upstreams()

Expected Behavior

Since APISIX is real-time, upstreams should be updated as soon as they are updated in the dashboard.

Error Logs

local upstreams, _ = upstream.upstreams()
upstream is a nil value

Steps to Reproduce

1- update the upstreams in the dashboard

Environment

• APISIX version : 3.8.0
• APISIX Dashboard version: 3.0.0-alpine

[ali-mahdavi-mehr]

When an upstream is deleted, this error occurs even if no route uses it.

etcd:
   endpoints:
     - "http://etcd:2379"

You might need to change it to the correct host instead of using etcd:2379, as DNS might not resolve correctly.

I set the value but no change occurred.
