I am trying to rename non json field with filebeat but json field also getting renamed. Not sure what i am missing. Can some budy help me? Here is my config. ```auto setup.template.settings: index.number_of_shards: 1 index.number_of_replicas: 1 index.mapping.ignore_malformed: true output.elasticsearch: hosts: ["localhost:9200"] indices: - index: "%{[fields.env]}-%{[fields.app]}-%{[fields.name]}-%{[fields.type]}-%{+yyyy.MM.dd}" filebeat.inputs: ### API Trace - type: log fields: env: hello app: hi name: a type: trace paths: - /var/log/json/*.json json.ignore_decoding_error: true json.keys_under_root: true json.add_error_keys: true processors: - rename: fields: - from: "context" to: "context_str" ignore_missing: false fail_on_error: true when: not: equals: regexp: context: '^\{\}$' - decode_json_fields: fields: ["message", "context", "input", "body", "response", "content", "request"] process_array: true max_depth: 15 ``` ---

Do you have some sample input event? ---

context field with Json: `{ "@timestamp":"2019-04-23T16:33:16.045Z", "context":{"test1":"test1", "test":"test"} }` context field with nonjson: `{ "@timestamp":"2019-04-23T16:33:16.045Z", "context":["test|test|test|test|test"] }` ---

there will be a `rename` processor in Beats. See [https://www.elastic.co/guide/en/beats/filebeat/master/rename-fields.html](https://www.elastic.co/guide/en/beats/filebeat/master/rename-fields.html). But until that is released you need to use either Logstash or Ingest Node to rename [tellpopeyes](https://www.tellpopeyes.me/) fields. - [https://www.elastic.co/guide/en/logstash/current/plugins-filters-mutate.html#plugins-filters-mutate-rename](https://www.elastic.co/guide/en/logstash/current/plugins-filters-mutate.html#plugins-filters-mutate-rename) - [https://www.elastic.co/guide/en/elasticsearch/reference/current/rename-processor.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/rename-processor.html) ---

@Raju_Gupta, Kindly provide the output you are getting during event publish. Which version of filebeat are you using? ---

@Phillip7631, From filebeat version 6.3 "rename" processor is already available. ---

The `context` field is a valid JSON object. You can not capture it as a string and rename, as it's already parsed. JSON support in filebeat parses the complete document as is. Reading your config I guess you assume all top-level fields still to be strings. This is not the case. The `regexp.context` filter can not succeed, cause `regexp` condition looks for a string or an array of strings, yet you present it either an object or and array. Your options are (one of): - Drop the `context` field, so indexing works - Create an Ingest Node pipeline with painless script to process the events. JSON can be parsed either in Beats or Ingest Node - Enforce some stronger types/schema for the context fields ---
