Kibana 7.16.3 in latest Firefox and Brave (chromium) browsers
steps to reproduce:
- go to app/management/ingest/ingest_pipelines
- create pipeline
- name: any
- add processor: grok
- field: message
- first pattern: ^%{GREEDYDATA:field1}$
- add pattern: ^%{GREEDYDATA:field2}$
- add
- click grok to edit the processor again
- add pattern: ^%{GREEDYDATA:field3}$
- now move the third pattern to the first position (drag & drop)
First pattern gets overwritten by the previous first pattern. If you have a complex pattern, you hardly notice this issue, but it will mess up your ingest pipeline.
