Having issue with sls deploy

Serverless Framework
,
1

I am using below dependencies and it works fine with sls offline. but when I try to deploy to aws lambda it gives me an Error: ENOENT: no such file or directory, lstat ‘{path_to_dir}/.webpack/.serverless’
.serverless dir is created to ‘{path_to_dir}/.serverless’

“dependencies”: {
“serverless-offline”: “^3.15.3”,
“serverless-webpack”: “^2.2.2”,
“webpack”: “^3.5.5”,
“webpack-node-externals”: “^1.6.0”
}

My webpack.conf.js is as below

var nodeExternals = require(‘webpack-node-externals’);

module.exports = {
    entry: './handler.js',
    // context: __dirname,
    node: {
        process:true,
        __filename: true,
        __dirname: true
    },
    target: 'node',
    module: {
        loaders: []
    },
    // output: {
    //     libraryTarget: 'commonjs',
    //     path: '.webpack',
    //     filename: 'handler.js', // this should match the first part of function handler in serverless.yml
    // },
    externals: [nodeExternals()],
};
