EntityAlreadyExists: Role with name chatbot-andrea-executor already exists

I am creating a Nodebot with claudiajs.

const botBuilder = require('claudia-bot-builder')
const excuse     = require('huh')

module.exports = botBuilder((req) => {
    return `Thanks for sending ${req.text}. Your message is very important to us, but ${excuse.get()}`
}) 

but when I am deploying to aws cloud.

claudia create --region us-east-1 --api-module app

I am getting this error:

I just find that even (if you need to) you can set the role in the deployment command:

claudia create --region us-east-1 --role chatbot-andrea-executor  --api-module app

You have to replace the name on collision after --role's flag. Also you are more curios about here is a good starting point about custom deployments.
