nvx opened a new issue, #12402: URL: https://github.com/apache/apisix/issues/12402
### Current Behavior When enabling `set_ngx_var` in the opentelemetry plugin apisix errors out during startup. This worked prior to PR #11940. Looking at https://github.com/apache/apisix/blob/3.13.0/apisix/cli/ops.lua#L554 it appears that the part of the code to setup the required nginx variable wasn't migrated to use plugin metadata and is still using plugin attributes. ### Expected Behavior _No response_ ### Error Logs ``` "2025/07/07 01:32:59 [error] 38#38: *291 lua entry thread aborted: runtime error: /usr/local/apisix/apisix/plugins/opentelemetry.lua:374: variable "opentelemetry_context_traceparent" not found for writing; maybe it is a built-in variable that is not changeable or you forgot to use "set $opentelemetry_context_traceparent '';" in the config file to define it first" ``` ### Steps to Reproduce Enable the opentelemetry plugin and set the following plugin metadata ``` "plugin_metadata": - "collector": "address": "127.0.0.1:4318" "request_timeout": 3 "id": "opentelemetry" "set_ngx_var": true ``` ### Environment - APISIX version (run `apisix version`): apache/apisix:3.13.0-debian - Operating system (run `uname -a`): Linux/Docker - OpenResty / Nginx version (run `openresty -V` or `nginx -V`): as per docker image - LuaRocks version, for installation issues (run `luarocks --version`): as per docker image -- This is an automated message from the Apache Git Service.
