Open API Error

[apolloraptor]

We are trying the Open API Manager for Confluence plug-in but we keep getting an error (tried v2.3.0 and 2.3.2). 

Error Message: 

{"messages":["malformed or unreadable swagger supplied"],"schemaValidationMessages":[{"level":"error","domain":"validation","keyword":"type","message":"instance type (string) does not match any allowed primitive type (allowed: [\"object\"])","schema":{"loadingURI":"#","pointer":""},"instance":{"pointer":""}}]}

  Occurs when I upload any swagger-2.0 JSON/YAML file, however open API 3.0 files work just fine.
