Warning 'Data and type mismatch found.' with 'date-time' format

[adsk-duszykf]

I get a warning: 'Data and type mismatch found.' with this response description:

DiffCreatedEvent:
  description: 'diff index created
  type: object
  additionalProperties: false
  properties:
    updatedAt:        { $ref: '#/components/schemas/Timestamp' }
  example:
    {
      "updatedAt": '2020-06-30T06:43:51.391Z',
    }
Timestamp:      { type: string, format: date-time, description: 'timestamp', example: '2020-06-30T06:43:51.391Z' }

but no warning with this:

  additionalProperties: false
  properties:
    updatedAt:        { type: string, format: date-time, description: 'timestamp', example: '2020-06-30T06:43:51.391Z' }

Thanks for raising this @adsk-duszykf

The warning seems to be raised by the OpenApi.Net library as it parses the description at https://github.com/microsoft/OpenAPI.NET/blob/29b1a1a9acbc65d7b2961b3f08e681a1e59d7c38/src/Microsoft.OpenApi/Validations/Rules/RuleHelpers.cs#L42C28-L42C52

Any chance you can post the issue at the https://github.com/microsoft/openAPI.NET repo for the team to investigate? @MaggieKimani1

Or we can simply transfer the issue @andrueastman ;)

Unfortunately we are very aware of this issue and are working hard to make the problem go away in v2. There are a range of issues with the way this particular validation works today and we have never found a good way of fixing it that didn't involve just ripping all the datatype mismatch errors out. The good news is that in V2 it will actually do proper, full JSON Schema validation of the examples.
