- OpenResty / Nginx version (cmd: `nginx -V` or `openresty -V`):
- etcd version, if have (cmd: run `curl http://127.0.0.1:9090/v1/server_info` to get the info from server-info API):
- apisix-dashboard version, if have: 2.8
- the plugin runner version, if the issue is about a plugin runner (cmd: depended on the kind of runner): skywalking8.7.0
- luarocks version, if the issue is about installation (cmd: `luarocks --version`):

Start by reviewing the attached error screenshot and reproducing an APISIX 2.9 Helm installation in the reported Amazon Linux environment, including the APISIX Dashboard and SkyWalking plugin runner versions. No file or test is named; inspect the chart templates and rendered configuration to identify the source of the recurring error and verify whether the final result explains or removes it without breaking functionality.
