Description

After I upgrade apisix from 3.5 to 3.10, apisix could not load upstream data any more.

Environment

• APISIX version (run apisix version): 3.10.0
• Operating system (run uname -a):
• OpenResty / Nginx version (run openresty -V or nginx -V):
• etcd version, if relevant (run curl http://127.0.0.1:9090/v1/server_info):
• APISIX Dashboard version, if relevant:
• Plugin runner version, for issues related to plugin runners:
• LuaRocks version, for installation issues (run luarocks --version):

[zsmlinux]

I discovered that this issue is caused by Apache APISIX PR #10233.

When I configure an upstream with service discovery using the APISIX Dashboard, it automatically generates _discovery_type and _service_name properties. However, according to Apache APISIX PR #10233, these properties are not permitted.
