Hello,

Trying to rename the fields [field][subfield] to [subfield] for all the dynamic **subfields** I receive under my **field**.

"field" : {  
"subfield\_1" : "value1",  
"subfield\_2" : "value2",  
.  
.  
"subfield\_n" : "value3"  
}

Expected output fields names to be ingested to ES for above nested JSON would be

"subfield\_1" : "value1",  
"subfield\_2" : "value2",  
.  
.

Regards,  
Sai
