uuid type does not serialize correctly

[ghost]

Recent changes introduced by #137 cause optional uuid types to be written to the wire as e.g. 'Some(c5bff7f0-b4df-475e-a331-f737424f013c)'. This is quite a tricky area but I would suggest: defaultArg theGuid Guid.Empty would potentially be more compatible, but this is a bit opinionated.

Workaround: It is possible to use DelegatingHandler (example https://github.com/fsprojects/SwaggerProvider/issues/132#issuecomment-557374506) to replace Some(guid) with guid.

Is this parameter in your schema specified as not required? What is the location for parameters? url/header/body?

It is defined as an optional header (X-Token). I can upload the part of the schema but it will be a few days til I can

minimal schema obtained. The schema is generated by swashbuckler:

Workaround:

type LoggingHandler(log:ILog, messageHandler) =
    inherit DelegatingHandler(messageHandler)
    // https://wizardsofsmart.wordpress.com/2014/05/13/how-to-use-base-sendasync-in-f-delegatinghandler/
    member private x.SendAsync' (request, cancellationToken) =
        base.SendAsync(request, cancellationToken)
    override this.SendAsync (request, cancellationToken) = task {
        // https://github.com/fsprojects/SwaggerProvider/issues/140
        let name = "X-GUID"
        if request.Headers.Contains name then
            let value = request.Headers.GetValues(name) |> Seq.head
            request.Headers.Remove name |> ignore
            request.Headers.Add(name,[value.Split([|'(';')'|]).[1]])
        return this.SendAsync' (request, cancellationToken)
