Welcome to the community.

Check you .conf and the template, especially the kubernetes.labels.app 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.*

Kubernetes labels map

type: object

here it is my conf file

input {
redis {
host => "elk-XXXX-XXX.amazonaws.com"
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".

[Sreecharanhope]

no we dont have that filed
