No support for specifying any type

[stojan-jovic]

Swagger spec:

Query:
  type: object
  required:
    - select
  properties:
    select:
      type: array
      items:
        type: string
    where:
      type: array
      items:
        type: object
        required:
          - name
          - operator
          - value
        properties:
          name:
            type: string
          operator:
            type: string
          value:
            oneOf:
              - type: string
              - type: number
              - type: boolean
              - type: array
                items: {}

It failed to validate array type for value property (other types are validated fine, when array is removed).

Using lib in combination with Falcon, error is:

Maybe I'm doing something wrong (?!), but not found in OpenAPI documentation any limitation for array in usage with oneOf, so I assume that above spec is valid and issue is definitely in the lib validation.

[stojan-jovic]

Ok, I figured out that this is not specifically related to oneOf.

Issue is with syntax to support any type in array:

type: array
items: {}

The same issue is with following syntax (i.e. allow any type for value parameter):

value: {}

All above formats should be allowed according to the official page for working with Data Types (section for the working with arrays and objects, part for any types, at the very end of the page).

Solution for my original issue would be something like this:

value:
  oneOf:
    - type: string
    - type: number
    - type: boolean
    - type: array
      items:
        oneOf:
          - type: string
          - type: number

I also have get your error for no obvious reason for me.

But on a lot of route I get:

TypeError: unsupported operand type(s) for /: '_io.TextIOWrapper' and 'str'

Hope this can help.
