I get the following error when using dynamic_templates, I'd like to map the fields with k8s.* as text and nested object field "network" as a flat_object.
I've tried using both regex and path_match but get the same error.
Can anyone let me know if I'm doing it correctly?

Note: I'm using OpenSearch 2.11 and they don't have documentation on dynamic_templates hence I've raised a topic here.
