WSO2 payload factory appending additional field with JSON request
I am creating a JSON payload in WSO2 ESB. But recently I have noticed while hitting the endpoint, it is adding some extra field at the start and end of the message body. Thus the JSON structure is getting changed and as result failing to generate actual result. The extra field can not be seen from normal logs but if you enable http wire log, you can notice these fields. I am pasting the code below and also the wire logs.
<payloadFactory media-type="json">
<format>
{
"ExtReference": "$8",
"MemberSubType":{
"MemberSubTypeId":"20",
"Name":"DD"},
"Region": "",
"PersonalDetails": {
"FirstName": "$9",
"LastName": "sample",
"MiddleName": "",
"DateOfBirth": "",
"GenderType": "",
"SalutationType":"",
"MemberStatus":""
},
"Address": [{
"AddressLine1": "$1",
"AddressLine2": "$2",
"HouseName": "",
"HouseNumber": "",
"Street": "",

"ContactDetails": [{

"Phone": "$10",
"MobilePhone": "$7",
"Fax": "$6",
"ContactDetailsType": ""

"PropertyValue":""
}]
}

while it is hitting the endpoint I logged the request enabling the wire.

See in the 2nd line of the logs shows a value 44d and in the 2nd last line a value zero appended which has not been served anywhere in payload. I have confirmed from the system owner, that for these two junk values only the request is getting failed. Kindly suggest a way out to get reed of these two fields. Thanks in advance.

You can use: <property name="DISABLE_CHUNKING" value="true" scope="axis2"/> before sending your request to the backend server.
This will work fine...

This zero at the end is related to the way the payload is returned to the client, which is the "chunked" transfer.
( See: https://en.wikipedia.org/wiki/Chunked_transfer_encoding)
In short, the 44d is simply the number of bytes that is part if this "chunk". The last "0" implies that there are no more chunks.
