Research direction

No source files or tests are named in the issue. Reproduce the response-schema validation with the shown YAML array schema and inspect the validation path that produces “Value id is not of type SchemaType.OBJECT.” Done means the error clearly identifies that the response value should be an array.

Written by the indexing model from the issue text.

Description

area/schema kind/bug/confirmed

Use case description.
Inside my schema yaml file I've specified that response from some URL handler would be an array of objects, e.g.:

      responses:
        "200":
          description: An array of provisioned Resource Records
          content:
            application/json:
              schema:
                type: array
                items:
                  $ref: '#/components/schemas/ResourceRecord'

I've also described what is ResourceRecord inside the same yaml file

For some reason the code returns an object, not an array
in this case the exception message from OpenAPI framework is a bit strange:

SchemaValidationError: Mimetype invalid: Value id is not of type SchemaType.OBJECT

id from error is the 1st attribute of my object (specified in yaml spec)

What is expected.
The expected error message is to complain that no array specified, array is missed, etc
