Trying to populate non string value into a string for variable

See original GitHub issue

This is a (Bug Report)

Description

What went wrong? I updated to the latest version of Serverless and I’m now getting an error when I invoke functions locally without adding the stage option in the command line.
What did you expect should have happened? The function should have been executed without an issue using the default stage as it was set up in the serverless.yml

provider:
  name: aws
  stage: dev
  custom:
    stage: ${opt:stage, self:provider.stage}

What was the config you used?

     OS:                 darwin
     Node Version:       6.10.3
     Serverless Version: 1.14.0

What stacktrace or error message from your provider did you see?

Ok “fixed” this… the config command I was running doesn’t need a --stage but the way I had set up my yml meant it would complain if it’s not there…

So I added --stage to the config command which fixed things…

I’m new to serverless and just got this same error when trying to login. Is there a fix here or something I need to configure to login and run deployments?

$ serverless login
