I have created lambda function on node.js which returns JSON.



It connected with API Gateway and worked well.



I want to connect it to amazon load balancer.



I tried it but it returns HTML page.



async function run(event)


let ret = ;

ret =
'statusCode': 200,
'statusDescription': '200 OK',
'headers':
'Content-Type': 'application/json'


ret.code = 200;
return ret;


exports.handler = run;


How to return JSON?
