Hi All ,getting error like this..."caused\_by" : {  
"type" : "array\_index\_out\_of\_bounds\_exception",  
"reason" : "Index 128 out of bounds for length 128",  
"caused\_by" : {  
"type" : "array\_index\_out\_of\_bounds\_exception",  
"reason" : "Index 128 out of bounds for length 128"  
}

while doing aggregation on nested Fields and its giving only for one particular document but data stored in that doc seems good as other have ....

here is the StackTrace of error:Caused by: java.lang.ArrayIndexOutOfBoundsException: Index 128 out of bounds for length 128

at org.Elasticsearch.search.aggregations.bucket.composite.CompositeAggregator$3.collect(CompositeAggregator.java:405) ~[Elasticsearch-7.6.2.jar:7.6.2]

And it is working fine without TopHits aggregation but whenever applied top hits aggregation its breaking and giving error like this..

here is the quey :

#query for currupt doc----field == PRICE\_CTRL ...

{

}  
}  
}  
}  
}  
}  
}  
}  
}
