Swagger editor says: is not exactly one from <#/definitions/parameter>,<#/definitions/jsonReference>

Question

I'm trying to define a swagger documentation for my API. Swagger editor keeps saying is not exactly one from <#/definitions/parameter>,<#/definitions/jsonReference> I checked the specification and a parameter should have name, in required, description and default if not in: body http://swagger.io/specification/#parameterObject

Thanks

There are two issues:

1) Parameters are missing a type, e.g. "type": "string".

2) default is not used with required parameters, it's only used with optional parameters. The default value is the value that the server uses if the client does not send this parameter. But if a parameter is required, the client must always send it and the default value is never used.
