kin-openapi version: v0.80.0
Hi, I'm trying out the new feature for validating request bodies with content type application/x-yaml but openapi3filter.ValidateRequest always returns the error: request body has an error: doesn't match the schema: unhandled value of type map[interface {}]interface {}.
Am I doing something wrong here (see also full example at the end) or is it a problem in the implementation?
What I saw so far is, that the request body is decoded here as type map[interface{}]interface{} using gopkg.in/yaml.v2. Later, during validation against the schema, this leads to the error because this type switch only expects map[string]interface{}, not map[interface{}]interface{}.
There is some ongoing discussion in the gopkg.in/yaml.v2 about the map key type, see for example here go-yaml/yaml#384.
