Cannot use import statement outside a module.

[Nakul Nagariya]

Describe the bug
I 'have build my application using your template, app is working fine in local, but when I'm trying to run this using serverless.yml and sls offline it says Cannot use import statement outside a module.

I'm not sure why this problem occurs but this is blocking me deploying my app.

Please suggest a way out.
