I’ve set up my project according to the `serverless-webpack` docs. My functions (written in ES6) work when invoked locally, but result in the following error when I deploy them to AWS:

```
{
    "errorMessage": "Unexpected token import",
    "errorType": "SyntaxError",
    "stackTrace": [
        "SyntaxError: Unexpected token import",
        "createScript (vm.js:56:10)",
        "Object.runInThisContext (vm.js:97:10)",
        "Module._compile (module.js:542:28)",
        "Object.Module._extensions..js (module.js:579:10)",
        "Module.load (module.js:487:32)",
        "tryModuleLoad (module.js:446:12)",
        "Function.Module._load (module.js:438:3)",
        "Module.require (module.js:497:17)",
        "require (internal/module.js:20:19)"
    ]
}

```

My current understanding is that Lambda should have recompiled the ES6 code according to my webpack.config.js settings before actually executing the code, but that doesn’t appear to be the case. Does anyone have any pointers?

webpack.config.js:  
const path = require(‘path’);  
const slsw = require(‘serverless-webpack’);  
const nodeExternals = require(“webpack-node-externals”);

```
module.exports = {
  entry: slsw.lib.entries,
  target: 'node',
  mode: 'development',
  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        use: 'babel-loader'
      }
    ]
  },
  externals: [nodeExternals(), 'pg', 'sqlite3', 'tedious', 'pg-hstore'],
  output: {
    libraryTarget: 'commonjs',
    path: path.join(__dirname, '.webpack'),
    filename: '[name].js'
  }
};

```

.babelrc:  
{  
“passPerPreset”: true,  
“presets”: [  
{ “plugins”: [“transform-runtime”] },  
{  
“passPerPreset”: false,  
“presets”: [“env”, “stage-3”]  
}  
]  
}

After 10 hours, discovered the problem: my Serverless cli was not updated.

Can you elaborate how do you solve this? I am having the same problem? the serverless version is the latest as well.

I am facing a similar issue:

The complete issue is here:[https://stackoverflow.com/questions/51687740/serverless-lambda-invoking-lambda-getting-no-errors-but-a-empty-response](https://stackoverflow.com/questions/51687740/serverless-lambda-invoking-lambda-getting-no-errors-but-a-empty-response)

And this is the error I am getting:

```auto
{
    "errorMessage": "Unexpected token (",
    "errorType": "SyntaxError",
    "stackTrace": [
        "Module.load (module.js:487:32)",
        "tryModuleLoad (module.js:446:12)",
        "Function.Module._load (module.js:438:3)",
        "Module.require (module.js:497:17)",
        "require (internal/module.js:20:19)"
    ]
}

```
