Running into this with v0.5.0 and v0.5.1 when I attempt to deploy. My AWS credentials are set in ~/.aws/credentials and I've successfully deployed with them using past versions of Serverless.

Serverless:   my-function-name: Missing required key 'Role' in params
/usr/local/lib/node_modules/serverless/node_modules/bluebird/js/release/async.js:49
        fn = function () { throw arg; };
                           ^

Hi @carolynnvu - Are you migrating a project over from a previous version? Do you have a iamRoleArnLambda variable defined in the stage.region.json variables file containing your Lambda's IAM Role ARN?

@carolynnvu

Hi @ac360. Yes, I'm migrating from a previous version. I see iamRoleArnLambda defined in my s-resources-cf-stage-region.json file.

@carolynnvu you might try adding the value for that output (in the CFT output tab, accessible from the console) to your s-variables-[stage].json (not sure this one works, see #791) or s-variables-[stage]-[region].json file. Something like:

{
  ...
  "iamRoleArnLambda": "[ARN_HERE]"
  ...
}

You may have it already defined somewhere in your project, such as your s-project.json.

@carolynnvu

@erikerikson I just saw your response now.

But I got it to work yesterday by removing the project from AWS and then doing a sls project install. Deploying worked without any issues after that.
