OpenAPI 3.1 compatibility: "examples" property not allowed / "type" property as an array not allowed

[Tithugues]

Describe the bug From OpenAPI 3.1, the example property is deprecated and examples is preferred and type property can be a string, but also an array of strings.

The examples property and the type as an array seem not to be supported.

To Reproduce

1. Create a YAML file in a project
2. Copy the following lines in the file:

   openapi: '3.1.0'
   info:
   version: '0.0.1'
   title: 'My API'
   paths:
   /my/route:
     get:
       operationId: MyRoute
       responses:
         200:
           description: 'Successful response.'
           content:
             application/json:
               schema:
                 type: object
                 properties:
                   a_property:
                     type: ['string', 'null']
                     examples:
                       - null
                       - "Hello world!"

3. See errors

Expected behavior I would expect examples and type as an array to be allowed in the editor part.

Screenshots Editor complains about those 2 properties:

On the other hand, the preview seems to "understand" the syntax:

Stack trace No exception.

Desktop (please complete the following information):

• Zalando OpenAPI Editor version: 1.3.0
• IDEA version: PhpStorm 2024.1.1 (Build #PS-241.15989.102, built on April 23, 2024)
• Java version: OpenJDK 64-Bit Server VM by JetBrains s.r.o.
• Operating System & version: Ubuntu 22.04

Additional context Swagger editor (https://editor-next.swagger.io) does not complain about this YAML file.

Am I wrong anywhere? Is the OpenAPI 3.1 not supported? If so, is it expected to be supported?

Thank you! :pray:

Regarding the examples, it seems it can't be used everywhere! Sorry for this mistake. :pray:

On the other hand, regarding the type type, I'm not sure I made a mistake.
