bug: upstream.upstreams() returns nil

ali-mahdavi-mehr commented 4 months ago

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

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

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.
