Hi ,
I am using above script to index the data in bulk, so when i am inserting one document at a time its working fine but with bulk its giving the exception as below :

"error":"JsonParseException[Unexpected character (':' (code 58)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')\n at [Source: [B@14abb68; line: 1, column: 18]]","status":500}

Kindly find below code which I am using for the same and do let me know what could be wrong over here.
