I tried to create a new ingest pipeline cloning from existing filebeat ingest pipeline and tried to add additional grok processor to add and modify fields. When tested the pipeline from simulation with single document on ingest pipeline page in Kibana, simulation result were as expected with added fields and modifications but the index created in the elasticsearch did not contain new field or modification i.e. added processors steps were performed on the incoming document. ELK stack version 8.13.4
Thanks
