Research direction

Start by reproducing the failure with the schema and request examples in the issue, focusing on array item validation with oneOf. Trace the validation path that raises UndefinedSchemaProperty for the package variant. Done means both image and package array items are validated against their matching schemas without the reported exception.

Written by the indexing model from the issue text.

Description

If you have multiple types (oneOf) of items in an array only the first is validated against:

schema

conditions:
  type: array
  items:
    oneOf:
      - type: object
        required:
          - image
        properties:
          image:
            type: string
        additionalProperties: false
      - type: object
        required:
          - package
        properties:
          package:
            type: array
            items:
              type: string
            minItems: 2

request

{'conditions': [{'image': 'data'}, {'package': ['info', 'data']}]}

Yields: openapi_core.schema.schemas.exceptions.UndefinedSchemaProperty: Undefined properties in schema: {'package'}
