anyOf with differing types in schema results in incorrect validation error

Do you have a reproducer?

Using the below schema, if I make the below request with an invalid field name such that if fails to match any of the anyOf types, I get the error, $.data.relationships.source.data.id: object found, string expected. However, the field can be either a string or an object.

Minimal reproducible schema

relationships:
  type: object
  required: [source]
  properties:
    source:
      anyOf:
        - type: object
          required: [data]
          properties:
            data:
              type: object
              required: [id]
              properties:
                id:
                  type: string
        - type: object
          required: [data]
          properties:
            data:
              type: object
              required: [id]
              properties:
                id:
                  anyOf:
                    - type: string
                    - type: object
                      required: [pId, rId]
                      properties:
                        pId:
                          type: string
                        rId:
                          type: string

Request body causing error

@slinkydeveloper can you have a look? Thanks!

Hi @therockstorm thanks for opening the issue, can you open the issue here? https://github.com/eclipse-vertx/vertx-json-schema

I think the reason is that we're just picking one of the validation failures https://github.com/eclipse-vertx/vertx-json-schema/blob/master/src/main/java/io/vertx/ext/json/schema/common/AnyOfValidatorFactory.java
