AWS Lambda Error: "Cannot find module '/var/task/index'"

Node.js Alexa Task Issue

I'm currently coding a Node.js Alexa Task via AWS Lambda, and I have been trying to code a function that receives information from the OpenWeather API and parses it into a variable called weather. The relevant code is as follows:

var request = require('request'); var weather = ""; function isBadWeather(location) {       var endpoint = "http://api.openweathermap.org/data/2.5/weather?q=" + location + "&APPID=205283d9c9211b776d3580d5de5d6338";       var body = "";       request(endpoint, function (error, response, body) {             if (!error && response.statusCode == 200) {                   body = JSON.parse(body);                   weather = body.weather[0].id;             }       }); }  function testWeather() {       setTimeout(function() {       if (weather >= 200 && weather < 800)             weather = true;       else             weather = false;       console.log(weather);       generateResponse(buildSpeechletResponse(weather, true), {});       }, 500); } 

I ran this snippet countless times in Cloud9 and other IDEs, and it seems to be working flawlessly. However, when I zip it into a package and upload it to AWS Lambda, I get the following error:

{     "errorMessage": "Cannot find module '/var/task/index'",     "errorType": "Error",     "stackTrace": [         "Function.Module._load (module.js:276:25)",         "Module.require (module.js:353:17)",         "require (internal/module.js:12:17)"     ] } 

I installed module-js, request, and many other Node modules that should make this code run, but nothing seems to fix this issue. Here is my directory, just in case:

- planyr.zip    - index.js    - node_modules    - package.json 

Does anyone know what the issue could be?

Fixed it! My issue was that I tried to zip the file using my Mac's built-in compression function in Finder.

If you're a Mac user, like me, you should run the following script in terminal when you are in the root directory of your project (folder containing your index.js, node_modules, etc. files).

zip -r ../yourfilename.zip * 

For Windows:

Compress-Archive -LiteralPath node_modules, index.js -DestinationPath yourfilename.zip
