Unable to deploy

I am following https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/nodejs-dynamodb-tutorial.html

and so I downloaded the zip of this repo and was trying to deploy it.

But I aam getting the following error all the time:
```

Invalid option specification (Namespace: 'aws:elasticbeanstalk:container:nodejs:staticfiles', OptionName: '/static'): Unknown configuration setting.

```

How can I solve it?
