Parsing "examples" fails

[brooksyott]

If you use the keyword "examples:", either in JSON or YAML, it fails.
In the case of YAML, an exception is thrown.
In the case of JSON,

Cannot create map at #/paths//smsmessaging/{apiVersion}/{userId}/inbound/subscriptions/get/responses/200/content/examples

and it omits it from the conversion.

I used the OpenAPI workbench to validate my findings.

Sample JSON that fails below:

Hey @brooksyott , thanks for the taking the time to report the issue. The problem you are running into is that the examples property in a media type object is a map and not an array. This was changed from v2, where it used to be an array. Also, now the examples object allows you to specify some metadata about the example.

[brooksyott]

Perhaps I gave a bad example. I may still be misunderstanding as well.

I believe from the openApi page on Swagger:
https://swagger.io/docs/specification/adding-examples/

The following should work:

openapi: "3.0.0"
info:
  description:  API for CPaaS 2.0 to use SMS related functions
  version: "0.2"
  title: CPaaS SMS API
  termsOfService: https://kandy.io
  contact:
    name: Kandy CPaaS API Team
    email: no.email@kandy.io
    url: https://kandy.io
servers:
  - url: https://cpaas-api20-kvs1.kandy.io/{cpaasRoot}/
    variables:
      cpaasRoot:
        default: cpaas
        description: Root folder name configured based on the deployment

paths:
  /smsmessaging/{apiVersion}/{userId}/inbound/subscriptions: 

    parameters:
      - in: query
        name: limit
        schema:
          type: integer
          maximum: 50
        examples:       # Multiple examples
          zero:         # Distinct name
            value: 0    # Example value
            summary: A sample limit value # Optional description
          max: # Distinct name
            value: 50   # Example value
            summary: A sample limit value # Optional description

When I put that into the workbench (or use the library), I get:
Failed to parse input: Unable to cast object of type 'Microsoft.OpenApi.Readers.ParseNodes.MapNode' to type 'Microsoft.OpenApi.Readers.ParseNodes.ListNode'.

If I change "examples" to "example", it does convert it without error?

[darrelmiller]

@brooksyott Yes, your example above should work. There is an error in the library. I will get that fixed ASAP. Thanks for the heads up.
The reason it works when you change to example is because we accept any structure under example, but that is not what you are trying to do in this case.

[brooksyott]

Really appreciate the quick response, thank you!!
