[jenreh]

yaml:

securityDefinitions:
  basicAuth:
    type: basic
  oauth:
    type: oauth2
    flow: application 
    tokenUrl: "/oauth/token"

Throws the following exception. When removing the oauth block eveything ist fine.

Exception:

The problem seems to be "type: oauth2"

Hello,

yes. The oauth2 scopes are required and must not be missing.

See: http://swagger.io/specification/#securitySchemeObject

Thank you, changing the yaml to

  oauth:
    type: oauth2
    flow: application
    tokenUrl: "/oauth/token"
    scopes:
      write:jarvis: schreibender Zugriff
      read:jarvis: lesender Zugriff

helped. A helpfull error message would be nice :-)

Yes, that's correct. Unfortunately I don't have much time atm. Feel free to create a Pull Request. :)
