Serverless invoke local - serverless/examples/aws-node-rest-api-with-dynamodb

Serverless Framework

I’d like to play around with serverless command invoke local and need your help.

Currently I use the example: https://github.com/serverless/examples/tree/master/aws-node-rest-api-with-dynamodb

$ npm install --save aws-sdk
$ npm install 
$ sls invoke local -f create --data '{ "text": "Learn Serverless" }'

  Syntax Error -------------------------------------------

  Unexpected token u in JSON at position 0

$ sls invoke local -f list

# no any output

Are there anything wrong with the command I run, any hints for me?
