This error seems to be related to mapping issues in Elasticsearch, below error found in logstash

Welcome to the community.

Check you .conf and the template, especially the field, you are writing the text type for example: "[kubernetes][labels][app]" => "pod1" instead of kubernetes.labels. as JSON. Check ECS. Also check the template, might be a wrong data type dynamically created during testing.


Kubernetes labels map

type: object

here it is my conf file

input {
redis {
host => ""
id => "staging"
data_type => "list"
key => "staging"
tags => [ "staging" ]

filter {
mutate {
gsub => ["message", "\x1B[([0-9]{1,2}(;[0-9]{1,2})?)?[m|K]", ""]
mutate {
remove_field => [ "@version", "_score", "_type"]

Can you show the full message? Should be the field named: "kubernetes".

no we dont have that filed
