yaml validation fails for functions with dash in name

[TheDeveloper]

The following works fine:

AWSTemplateFormatVersion: '2010-09-09'
Transform: 'AWS::Serverless-2016-10-31'
Resources:
  FunctionName:
      Type: 'AWS::Serverless::Function'
      Properties:
        Handler: index.handler
        Runtime: nodejs6.10

But when the function name contains a dash, it produces an error:

AWSTemplateFormatVersion: '2010-09-09'
Transform: 'AWS::Serverless-2016-10-31'
Resources:
  Function-Name:
      Type: 'AWS::Serverless::Function'
      Properties:
        Handler: index.handler
        Runtime: nodejs6.10

ERROR: Failed to read the resources line numbers. This usually means that the template contains invalid indentation. Please check it and try again

This is indeed an invalid template - http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/resources-section-structure.html. LogicalIDs cannot contain dashes.

I completely agree this error is super misleading. We are rewriting goformation now (the package that does template validation). All of these quirks should soon vanish. You will get a silky smooth experience (or I hope so 😀 )

Closing this Issue because it is a user error.

Thanks for the info @sanathkr !
