Hey all,

In my openapi-model:
      properties:
        ...
        occurrence:
          oneOf:
            - type: array
              items:
                type: string
            - $ref: "occurrence.yaml#/Occurrence"

works fine. However, this fails:
 
      properties:
        ...
        occurrence:
          oneOf:
            - type: array
              items:
                $ref: "occurrence.yaml#/Occurrence"
            - $ref: "occurrence.yaml#/Occurrence"

giving this error (exception):

I fail to see the problem...

Where do you use this schema? In a request body?

Yes... in a request body.

This is unexpected, can you open an issue on vertx-web with a simple reproducer? Thank you :)

my suggestion is you to try it with an updated version of parser since you are using $ref. there was a lot of fixes on this matter:

        <dependency>
            <groupId>io.swagger.parser.v3</groupId>
            <artifactId>swagger-parser</artifactId>
            <version>2.0.12</version>
        </dependency>
