Custom code parsing issue- Request Entity Too Large - Oracle MCS - node.js

Question

Hi I am facing an issue while accessing custom api using Oracle MCS
{
"message": "Custom Code Problem parsing JSON: request entity too large"
}
This occur while calling an api with request containing a byte array of an image.
my code given below
service.post('/mobile/custom/meraasmcs/documentofrecords/updateemiratesid',function(req,res){
console.info("Request Before Api call=>"+req);
var connector = '/documentofrecords/updateemiratesid'
commonHandler.CommonHandlerPostMethodFunction(
req,res,connector)
commonHandler.js
module.exports = {
CommonHandlerPostMethodFunction:
function (req, res, connector) {
/*
* Description : This function handles all the request and response
* Output : Returns a json content success message
* Author : Anand Raj
* Created Date : 10/10/2016
*/
var app = express();
var newReqBody=app.use(bodyParser.json({limit: '50mb'}));
console.info('New ReqBody=>'+newReqBody);
var errorMsg;
var finalResponse;
var headerIndex = JSON.stringify(
req.headers).search('application/json');
var versionNumberIndex = JSON.stringify(
req.headers).search('x-api-version');
var reqBody = JSON.stringify(req.body);
console.info('header ' + JSON.stringify(req.headers));
console.info('version index ' + versionNumberIndex);
console.info('version number ' + req.headers['x-api-version']);
console.info('Req body ' + reqBody);
res.header('Access-Control-Allow-Origin','*'); // To overcome cross origin issue in Windows platform
if (0 > headerIndex) {
finalResponse = jbuilder.encode(function (json) {
json.set('Response', function (json) {
json.set('responseCode', '415');
json.set('responseMessage', 'Unsupported media-type');
});
});
res.status(415).send(finalResponse);
res.end();
} else if (reqBody === '{}') {
finalResponse = jbuilder.encode(function (json) {
json.set('Response', function (json) {
json.set('responseCode', '400');
json.set('responseMessage', 'Malformed request body');
});
});
res.status(400).send(finalResponse);
res.end();
} else if (0 > versionNumberIndex) {
finalResponse = jbuilder.encode(function (json) {
json.set('Response', function (json) {
json.set('responseCode', '400');
json.set('responseMessage', 'Version Number missing');
});
});
res.status(400).send(finalResponse);
res.end();
} else {
/* request part */
var versionNumber = req.headers['x-api-version'];
var optionsList = {
uri: '/mobile/connector/MeraasAllConnector'+connector,
body: reqBody,
headers: {
'Content-Type': 'application/json',
'X-API-Version': versionNumber
}
};
/* handler part */
var handler = function (error, response, body) {
if (error) {
if ('message' in error) {
errorMsg = error.message;
//res.send(500, errorMsg);
//res.end();
finalResponse = jbuilder.encode(function (json) {
json.set('Response', function (json) {
json.set('responseCode', '500');
json.set('responseMessage', errorMsg);
});
});
res.status(500).send(finalResponse);
res.end();
} else {
finalResponse = jbuilder.encode(function (json) {
json.set('Response', function (json) {
json.set('responseCode', '408');
json.set('responseMessage', 'Response Timed Out');
});
});
res.status(408).send(finalResponse);
res.end();
}
} else {
if (response.statusCode !== 200) {
finalResponse = jbuilder.encode(function (json) {
json.set('Response', function (json) {
json.set('responseCode', response.statusCode);
json.set('responseMessage', response.message);
});
});
res.status(response.statusCode).send(finalResponse);
res.end();
} else if(response.statusCode==401){
finalResponse = jbuilder.encode(function (json) {
json.set('Response', function (json) {
json.set('responseCode', '401');
json.set('responseMessage', 'Authorization Required.');
});
});
res.status(401).send(finalResponse);
res.end();
}
else {
res.status(200).send(body);
res.end();
}
}
};
req.oracleMobile.rest.post(optionsList, handler);
}
}
};
Package.json
{
"name" : "meraasmcs",
"version" : "1.47.0",
"description" : "Contains all the custom Apis for Meraas Mobile App",
"main" : "meraasmcs.js",
"dependencies":
{
"jbuilder":"0.0.4",
"body-parser":"1.15.2",
"express":"4.14.0"
},
"oracleMobile" : {
"dependencies" : {
"apis" : { },
"connectors" : {"/mobile/connector/MeraasAllConnector":"1.0"}
}
}
}
If i reduce the size of image then pass its corresponding byte array, then there response will be success.
I checked related questions, all it says
var bodyParser = require('body-parser');
app.use(bodyParser.json({limit: '50mb'}));
app.use(bodyParser.urlencoded({limit: '50mb', extended: true}));
But i tried that also. Could anyone please help me??
Sample Request
{
"P_PERSON_ID": 31441,
"P_LOGIN_PERSON_ID": 31441,
"TIME_STAMP": null,
"P_EMIRATES_ID_TAB": [{
"DocumentExtraInfoId": "",
"ValidFrom": "2016-11-23",
"ValidTo": "2016-11-24",
"CardNumber": "Ggv4"
}],
"P_ATTACHMENT_TAB": [{
"Title": "image.jpg",
"DocumentId": null,
"DeleteFlag": "N",
"Description": "Testqwe",
"AttachmentName": "Test",
"FileData": "",
"AttachmentType": "image/jpeg"
}]
}
Issue comes when the length of the value of FileData is too large.
Thanks in advance
