How to define an array of objects in OpenAPI 3.0?

Question

I'm trying to add an object in an array, but this seems not be possible. I've tried the following, but I get always the error:

Property Name is not allowed.

This is shown for all items defined in the devices array. How can I define items in an array in OpenAPI?

You need to add two extra lines inside items to specify that the item type is an object:

            devices:
              type: array
              items:
                type: object      # <----------
                properties:       # <----------
                  Name:
                    type: string
                  descripiton:
                    type: string
                  Number:
                    type: integer
                  enabled:
                    type: boolean
