Cfn-python-lint: Template format error: Every AllowedValues member must be a list

[dragonfly-net]

cfn-lint 0.26.2

Checking .yaml file, block

Parameters:
  Env:
    Type: "String"
    Description: "Environment"
    Default: "staging"
    AllowedValues:
            staging
            mock
            production
            DEVOPS

Lint says no errors, but when run aws cloudformation:
An error occurred (ValidationError) when calling the CreateStack operation: Template format error: Every AllowedValues member must be a list.
