amazon web services - How to deploy a graphql api built with express to AWS serverless?

Question

I have been trying to deploy a backend api service made with graphql api and express to Amazon web services. This is my folder structure

Graphql-api
       -src
           -index.js
       -serverless.yml
       -index.js(this only contains an import statement of the src folder)

The serverless.yml looks like this

service: graphql-api

provider:
  name: aws
  runtime: nodejs12.x
  lambdaHashingVersion: 20201221

functions:
  api:
    handler: src/index.handler
    events:
      - http:
          path: graphql
          method: ANY
          cors: true
            

And I have exported this handler in my src/index.js file

`const awsServerlessExpress = require('aws-serverless-express');
const app = require('./app');

const server = awsServerlessExpress.createServer(app);

exports.handler = (event, context) => awsServerlessExpress.proxy(server, event, context);`

But when I run serverless deploy and get the endpoint url which is: https://nir4749aal.execute-api.us-east-1.amazonaws.com/dev/graphql I get a message saying internal server error. I can't figure out what I am doing wrong. This is my first time trying to deploy to AWS. Any help or suggestion would help thanks in advance.

-----UPDATE-------- This are the logs from lambda

{
    "errorType": "Runtime.UserCodeSyntaxError",
    "errorMessage": "SyntaxError: Cannot use import statement outside a module",
    "stack": [
        "Runtime.UserCodeSyntaxError: SyntaxError: Cannot use import statement outside a module",

    ]
}

It will probably be easier to debug if you check your AWS Lambda logs. Where is your app folder?
