Wrong use of discriminator feature in OpenAPI specification

[apibugsreporting]

Bug Description

The discriminator feature is being incorrectly used in the OpenAPI specification.

See screenshot.

The discriminator property should be an object with a property called propertyName, which should contain the discriminator property (i.e., "type"). Moreover, the discriminator feature should be used in conjunction with anyOf or oneOf keywords, but none of these are used. For references on how to use the discriminator feature in OpenAPI, take a look at:
