Bug: sam local invoke "Cannot find module 'index'" (happens when running from docker container only)

### Description:
When doing a `sam build` followed by a `sam local invoke` on a simple hello world lambda (nodejs16) everything works fine on windows but fails on linux (docker container, ubuntu:jammy-20220801).

### Steps to reproduce:
Install nodejs 16 (although same observed on 20 as well). Create a small helloWorld.js lambda, create a basic template.yaml, run sam build, run sam local invoke.

```

Description: A simple Hello World Serverless project
Resources:
HelloWorld:
Type: AWS::Serverless::Function
Properties:
Runtime: nodejs16.x
Handler: index.handler
CodeUri: .
```

```
`'use strict';

// A simple hello world Lambda function
exports.handler = (event, context, callback) => {

console.log('LOG: Name is ' + event.name);
callback(null, "Hello " + event.name);

}
```

### Observed result:
On windows:

On jammy docker container:

same happens with node 16.13 as well...

### Additional environment details (Ex: Windows, Mac, Amazon Linux etc)

docker container works on the same folder as windows with parent folder being mounted as volume.
