Operation parameters array with minItems can cause a 500 Internal Error

[tavantzo]

Hi,

according to the swagger specification the parameter object can have defined minItems but when I'm using it, the swagger editor, through the swaggerhub at least, badge turns to red (ERROR) while the swagger validate says that the document contains no errors.

Of course this is a minor issue but it can cause a headache at someone as it gave at me.

Thanks for opening the ticket. Apparently, there's a bug with the version of the json schema validator that use, and the fix is as simple as upgrading it. We'll push this fix to production soon.
