Logstash container fails to start

My `Elasticsearch, Logstash and Kibana` stack setup is based on Docker Compose and the version is - `8.15.2`.

`Logstash` container always fails to start and throws the following error.

```
logstash | ERROR: Failed to load settings file from "path.settings". Aborting... path.setting=/usr/share/logstash/config, exception=LogStash::ConfigurationError, message=>Cannot evaluate `${xpack.monitoring.elasticsearch.password}`. Replacement variable `xpack.monitoring.elasticsearch.password` is not defined in a Logstash secret store or as an Environment entry and there is no default value given.

```

It seems that `Logstash` cannot find or evaluate the variable `${xpack.monitoring.elasticsearch.password}` which was working fine with `v8.6.2` before the upgrade and it is working fine until with `Logstash v8.12.2`.

In the following release notes page - [Logstash 8.15.2 Release Notes | Logstash Reference [8.15] | Elastic](https://www.elastic.co/guide/en/logstash/current/logstash-8-15-2.html) I could see that `docker env variables` related issues are fixed with`v8.15.2` but it is not working as expected like old `v8.12.2` and getting same above errors, when i start the container.

Please let me know whether I should wait for the next release?
