@Kok Ching Hoo Even you don't need to use jolt transform processor to get only the entry array as the flow file content. We can achieve the same result by using split json processor in more easy way. Configure split json processor as JsonPath Expression $.*.*.*.* By using above json path expression it doesn't matter even if header value changed,array entry has been changed to entry1,exit ... etc until you are having same structure of the json message(same dependency will be applicable by using jolt also), this method will work we are going to split the array it self and then use the splits relation to connect to the next processors.
