Problems cloning events

[osvaldo_pina]

I´m trying to clone events that originate from splunk connector for kubernetes using the following configuration in props.conf and transforms.conf:

[(?::){0}*]
TRANSFORMS-logs_java=clone_trace

[trace]
TRANSFORMS-indice=indice_trace

tranforms.conf

[clone_trace]
REGEX=.
CLONE_SOURCETYPE=trace

[indice_trace]
REGEX=.
DEST_KEY=_MetaData:Index
FORMAT=jaeger_trace

For some reason some events are not beeing cloned. 

Any ideas?
