jonathan-dev opened a new issue, #10389:
URL: https://github.com/apache/apisix/issues/10389
### Current Behavior
I am running the image `apache/apisix:3.6.0-debian` with almost standard
settings for the opentelemtry plugin:
```
plugin_attr:
opentelemetry:
resource:
service.name: APISIX
tenant.id: business_id
collector:
address: otel-collector:4318
request_timeout: 3
request_headers:
foo: bar
batch_span_processor:
drop_on_queue_full: false
max_queue_size: 6
batch_timeout: 2
inactive_timeout: 1
max_export_batch_size: 2
```
plugin section for route:
```
"plugins": {
"opentelemetry": {
"disable": false,
"sampler": {
"name": "always_on"
}
},
```
looking at the apisix logs I get the following error:
```
2023/10/24 10:32:00 [error] 60#60: *1448554 lua entry thread aborted:

```
I also failed to get the logging in place that is described
[here](https://apisix.apache.org/blog/2023/10/05/release-apache-apisix-3.6.0/#support-the-use-of-nginx-variables-in-opentelemetry-plugin)
here I'm not sure If I need to put the http section in the top level or under
the `nginx_config: ` (when i put it there I get errors and when its on the root
level I get nothing).
### Expected Behavior

working plugin
### Error Logs
mentioned above
### Steps to Reproduce
startup apisix and send request to route that has the plugin setup
