I am using remove_field , but it is still showing that field in kibana. For eg- tags

Maybe the [tags] field is added after that mutate field executes.
Thanks for the reply. I figured out the issue was because of multiple conf files that were present in the conf.d directory because of which tags field was coming from another conf file. I Set up different pipelines for other conf files and it's working now.
