fs.readFileSync('moviedata.json', 'utf8') will look for moviedata.json in the directory from where you ran your application, not in the directory where your MoviesLoadData.js file is located.
Suppose you ran node aws/MoviesLoadData.js from /Users/dortiz/Documents/NodeJS/pruebas/zw, fs.readFileSync('moviedata.json', 'utf8') would look for moviedata.json in /Users/dortiz/Documents/NodeJS/pruebas/zw, not in /Users/dortiz/Documents/NodeJS/pruebas/zw/aws
If you were to run your script with my given example, you'd need to prepend the path to the json file to correctly reference it.
fs.readFileSync(__dirname + '/moviedata.json', 'utf8')
I'm not sure how you run your code, so my example may not work in your codebase, but hopefully understanding where you went wrong will help debug your code.
