Error converting value "meetNow" to type 'Microsoft.Graph.Agents.SchedulingService.MeetingType'. Path 'meetingType'

    {
        IAuthenticationProvider GetAuthenticationProvider()
        {
            return new DelegateAuthenticationProvider(async request =>
            {
                request.Headers.Add(HttpConstants.HeaderNames.ScenarioId, scenarioId.ToString());
                request.Headers.Add(HttpConstants.HeaderNames.ClientRequestId, Guid.NewGuid().ToString());

                await this.requestAuthenticationProvider
                    .AuthenticateOutboundRequestAsync(request, tenantId)
                    .ConfigureAwait(false);
            });
        }

        var statelessClient = new GraphServiceClient(this.graphEndpointUri.AbsoluteUri, GetAuthenticationProvider());
        var meetingRequest = statelessClient.Communications.OnlineMeetings[meetingId].Request();

        **var meeting = await meetingRequest.GetAsync().ConfigureAwait(false);**

        return meeting;
    }

Start with the shown GraphServiceClient Communications.OnlineMeetings[meetingId].Request().GetAsync() call and the reported meetingType conversion error. Check the response data and the MeetingType definition to identify the incompatible value; done means the request can deserialize successfully without this error.
