The field value is duplicated in independent Stream forwarder. Is there a workaround?
This looks like INDEXED_EXTRACTIONS = JSON
on UF side and KV_MODE = auto
(This is default) or KV_MODE = json
on search head is present and due to that it is extracting JSON event twice.
You need to set KV_MODE = none
on search head for your sourcetype so search head will not extract this JSON event again.
On SH props.conf
[yoursourcetype]
KV_MODE = none
Is this forwarded with useAck = true
set on the forwarders outputs.conf?
Scratch my comment - i misread 'field duplicated' as 'event duplicated'
