This spec DOES NOT render: openapi: 3.0.0 info: title: test version: 1.0.0 paths: '/test': get: summary: test responses: '200': description: test content: application/json: schema: type: object properties: entries: type: string The editor shows this error message: Unable to render this definition The provided definition does not specify a valid version field. Please indicate a valid Swagger or OpenAPI version field. Supported version fields are swagger: "2.0" and those that match openapi: 3.0.n (for example, openapi: 3.0.0). This spec DOES render.
