AWS Lambda Function is returning Handler 'handler' missing on module 'index'

Solution 1
In export.handler
, you are not referencing the index
function, but the result of its execution. I guess you want to export the function itself.
let index = function index(event, context, callback) {
//some code
}
exports.handler = index;
Or maybe directly
exports.handler = function index(event, context, callback) {
//some code
}
Solution 2
What you can do is to declare your function as the exports.handler. When your function exports to lambda, it comes with the namespace.
exports.handler = function(event, context) {
//code
}
You can ignore the callback if you want fast code.
Solution 3
You may have incorrectly specified your handler as "index.js" instead of "index.handler"

Consider following code -
function index(event, context, callback) { //some code } exports.handler = index(); { "errorMessage": "Handler 'handler' missing on module 'index'" }
This is my function which is having business logic. My javascript file name is
index.js
.Whenever I test this code on aws lambda, It gives following
log(failed)
.
