If you post a screen shot of an event in Kibana the screen shot is not searchable. It is not accessible to the visually impaired. I cannot copy and paste the message field to a machine running logstash, so that I can actually try things and give you a working solution. Instead I can make suggestions about what you can try.
Help us to help you. Instead of posting a screenshot, expand the event in Discover and click on the JSON tab, then copy and paste the JSON. Redact as necessary, without changing the structure. Select the JSON in the edit pane and click on </> in the toolbar above the edit pane, so that the formatting of the JSON is preserved.
