Incorrect type set for AnyType Schemas

[spacether]

When parsing this v3.0.1 schema:

openapi: 3.0.1
info:
  title: ping test
  version: '1.0'
servers:
  - url: 'http://localhost:8000/'
paths:
  /ping:
    get:
      operationId: pingGet
      responses:
        '201':
          description: OK
components:
  schemas:
    AnyValue: {}
    AnyValueWithDesc:
      description: Can be any value - string, number, boolean, array or object.
    AnyValueNullable:
      nullable: true
      description: Can be any value, including `null`.
    AnyValueModel:
      description: test any value
      type: object
      properties:
        any_value:
          $ref: '#/components/schemas/AnyValue'
        any_value_with_desc:
          $ref: '#/components/schemas/AnyValueWithDesc'
        any_value_nullable:
          $ref: '#/components/schemas/AnyValueNullable'
    AnyValueModelInline:
      description: test any value inline
      type: object
      properties:
        any_value: {}
        any_value_with_desc:
          description: inline any value
        any_value_nullable:
          nullable: true
          description: inline any value nullable
        map_any_value:
          additionalProperties: {}
        map_any_value_with_desc:
          additionalProperties: 
            description: inline any value
        map_any_value_nullable:
          additionalProperties:
            nullable: true
            description: inline any value nullable
        array_any_value:
          items: {}
        array_any_value_with_desc:
          items: 
            description: inline any value
        array_any_value_nullable:
          items:
            nullable: true
            description: inline any value nullable

swagger-parser incorrectly defines the type of the schemas:

• map_any_value as object when it should be null
• map_any_value_with_desc as object when it should be null
• map_any_value_nullable as object when it should be null
• array_any_value as array when it should be null
• array_any_value_with_desc as array when it should be null
• array_any_value_nullable as array when it should be null

Using swagger-parser 2.0.26
For one of them here is the shown value of the schema

map_any_value -> {MapSchema@2888} "class MapSchema {
    class Schema {
        type: object
        format: null
        $ref: null
        description: null
        title: null
        multipleOf: null
        maximum: null
        exclusiveMaximum: null
        minimum: null
        exclusiveMinimum: null
        maxLength: null
        minLength: null
        pattern: null
        maxItems: null
        minItems: null
        uniqueItems: null
        maxProperties: null
        minProperties: null
        required: null
        not: null
        properties: null
        additionalProperties: class Schema {
            type: null
            format: null
            $ref: null
            description: null
            title: null
            multipleOf: null
            maximum: null
            exclusiveMaximum: null
            minimum: null
            exclusiveMinimum: null
            maxLength: null
            minLength: null
            pattern: null
            maxItems: null
            minItems: null

This ticket will be solved when 3.1 branch is merged.

Using swagger-parser 2.0.31

This issue is also happening for:

openapi: 3.0.3
info:
  title: openapi 3.0.3 sample spec
  description: sample spec for testing openapi functionality, built from json schema
    tests for draft6
  version: 0.0.1
paths: {}
components:
  schemas:
    PropertyRefsContainingComponentSchema:
      properties:
        foo:
          $ref: '#/components/schemas/PropertyRefsContainingComponentSchema'
      additionalProperties: false

PropertyRefsContainingComponentSchema type should be unset but it is incorrectly set to object

This should be fixed in #1768, see this comment.
