thanks @aldex32 . i believe this is technically a breaking change correct?

Hey @jsdevel , yes it is a breaking change. I can avoid it buy making it backward compatible like this:

  componentSchemas?: IJsonSchema[] | { [key: string]: OpenAPIV3.ReferenceObject | OpenAPIV3.SchemaObject; };

But I am not sure if the type IJsonSchema[] is/was correct. Also all the tests I see in this project are not assigning any array to this field. Unfortunately the tests are not type checking the arguments passed to the constructor of OpenAPIRequestValidator and this probably was the reason of not catching the wrong type.

@aldex32 breaking change doesn't scare me. is this in line with th OpenAPI schema?
