Invalid Enum Syntax

[cnizzardini]

Describe the bug

Enum properties are showing as "Structural error" in swagger editor

To Reproduce
Create an enumerated type in your database and create a route for it. The enum is produced incorrectly:

                  the_model:
                    items:
                      type: object
                      properties:
                        an_enum_property:
                          type: string
                          enum:
                            Value: Value
                            Value2: Value2

Expected behavior

                  the_model:
                    items:
                      type: object
                      properties:
                        an_enum_property:
                          type: string
                          enum:
                            - Value
                            - Value2
