Logstash container fails to start

[mohanss08]

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 I could see that docker env variables related issues are fixed withv8.15.2 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?
