External schema always true

[uLan08]

Hi, I am using an external schema from a swagger file but when I validate data, it always return true.

The code

	const swagger = YAML.load('./src/swagger.yaml')
	const validate = validator({
		required: true,
		type: 'array',
		items: {
			$ref: '#/definitions/PostItem'
		}
	}, { verbose: true, schemas: { definitions: swagger.definitions })
	const result = validate(items)
	return { result, errors: validate.errors}

I also have tried loading in the whole swagger file with schemas: swagger.

This is PostItem definition in yaml format

  PostItem:
    allOf:
      - $ref: '#/definitions/Item'
      - type: object
        required:
          - type
          - quantity
        properties:
          type:
            $ref: '#/definitions/Type'
          quantity:
            type: integer
            minimum: 0 

I have tried putting in the schema manually and it was validating it correctly. I really don't want to rewrite parts of my schema just for this.
