Hi all

Logstash stops every time with this error:

[ERROR][logstash.agent           ] Failed to execute action {:action=">LogStash::PipelineAction::Create/pipeline_id:pscheduler," :exception=>"Java::JavaLang::IllegalStateException", :message=>"Unable to configure plugins: Cannot evaluate `${opensearch_output_host}`. Replacement variable `opensearch_output_host` is not defined in a Logstash secret store or an environment entry and there is no default value given.", :backtrace=>["org.logstash.config.ir.CompiledPipeline.<init>(CompiledPipeline.java:120)"

Does anyone know how to fix this ?

Regards

Johann
