aws lambda: test event configuration: Error in JSON event

Question

I have deployed a node js app to AWS lambda. I have the following code in my test event :

function getRoutes(callback){
    request('http://localhost/php-rest/api.php/routes?filter=route_short_name', function(error, response, body) {
        if (!error && response.statusCode == 200) {
            message = JSON.stringify(JSON.parse(body));
            return callback(message, false);
        } else {
            return callback(null, error);;
        }
    });
}

app.get('/getRoutes', function(req, res) {

    getRoutes(function(err, data){
        if(err) return res.send(err);
        res.send(data);
    });

});

I got the following error when I tried to save that:

There is an error in your JSON event. Please correct it before saving.

Test events in lambda support only the json format. It defines the event that is passed as an argument to a lambda handler. — Jay

It only use to pass the arguments into lambda function as @JaeyeonBaek said. So that it is better if you can post the lambda handler code here. — SamPiy93

so here you don't have to pass any parameters. therefore just keep the default json which is inside the test and save it by giving a name and run the test after that. So you will get a success or error message after completion. There you can see the error message if you have any errors. — SamPiy93

So lambda function is the handler code right? You have deployed it and that's because you get the test functionality for that lambda function. Isn't it? Did you go through the Create Function wizard? — SamPiy93

How about seeing the manual first? docs.aws.amazon.com/lambda/latest/dg/… — Jay

This is the configuration of lambda function you have created. So click on the lambda function first. After that you will get a window called function code. There you have to write you handler. After that you can test like you did before.

Oh, so I just upload the lambda function as a zip file?

So what is the output you got?

It can't find express module. Did I have to upload node_modules with the rest of my code?
