OpenAPI testing : schema not found for

[romch007]

I am trying to test an endpoint against OpenAPI spec. The spec part:

paths:
  /groups/{id}:
    parameters:
      - in: path
        name: id
        schema:
          type: integer
        required: true
        description: ID of group
    delete:
      summary: Delete a group
      tags:
        - Groups
      security:
        - bearerAuth: []
      responses:
        '404':
           $ref: "#/components/responses/NotFoundError"
        '204':
          description: Group deleted successfully

The tests:

test('should delete a group', async ({ assert, client }) => {
  const group = await GroupFactory.create()

  const response = await client.delete(`/groups/${group.id}`).loginAs(adminUser)
  response.assertStatus(204)
  response.assertAgainstApiSpec()

  const deleteGroup = await Group.find(group.id)
  assert.isNull(deleteGroup)
})

When I run it I get: Error: schema not found for {"path":"/groups/4","method":"delete","status":204}
I have other tests and spec with the exact same path for method GET, POST and PUT that work fine, but this one just don't.

EDIT: OpenAPI assert fails on all endpoints that have a empty response body. Link to related issue.

Okay, so seems to be an issue with the underlying library (as you mentioned). So the best is to fix it with that library and update Japa dependencies.
