Customize OpenSearch Templates
OpenSearch indexes are marked as strict that implies dynamic field addition to the indexes is not allowed. If you wish to customize the indexes such as RPA-trans-*, SE-actvttrack-* and so on, you need to update the respective template.
Access <Installation Directory>/< AssistEdgeAutomation > runtime > logstash > logstash-8.9.0 > config > templates folder to find the templates.
