Unable to create ToDo Task using Graph API v1.0

Question

Unable to create ToDo Task using Graph API v1.0

Mahesh Tibrewal 51

I am trying to use the ToDo Task feature of graph api v1.0 to create a task using the following code

var result = graphServiceClient.Users[outlookUserId].Todo.Lists[listid].Tasks.Request().AddAsync(todoTask).Result;

However, I am getting the following the error:

Code: invalidRequest
Message: A type named 'microsoft.toDo.todoTask' could not be resolved by the model. When a model is available, each type name must resolve to a valid type.
Inner error:
Code: InvalidModel
AdditionalData:
date: 2020-11-25T09:41:04
request-id: 39794548-8f63-443e-a8bc-76ad6091dc8d

ClientRequestId: 39794548-8f63-443e-a8bc-76ad6091dc8d

To resolve above, I had set the odatatype of todoTask to null, but got another exception:

Code: invalidRequest
Message: A type named 'microsoft.toDo.dateTimeTimeZone' could not be resolved by the model. When a model is available, each type name must resolve to a valid type.
Inner error:
Code: InvalidModel
AdditionalData:

ClientRequestId: 0780add8-3f17-40c5-a92b-e9e62ad08bf8

To resolve above I set the odatatype of all data members of todoTask of type DateTimeZone to null, but then getting the following exception:

Code: invalidRequest
Message: A type named 'microsoft.toDo.itemBody' could not be resolved by the model. When a model is available, each type name must resolve to a valid type.
Inner error:
Code: InvalidModel
AdditionalData:

ClientRequestId: 5bafbcab-5090-47b5-ac8e-8c96ec1d6592

To resolve above, I set the odatatype of todoTask body to null, but now I am getting following exception which I am unable to resolve:

Code: generalException
Message: Internal Server Error
Inner error:
AdditionalData:
date: 2020-11-25T09:48:23
request-id: f5d52f43-c0b4-425e-83ec-652fadb7abf9
client-request-id: f5d52f43-c0b4-425e-83ec-652fadb7abf9
ClientRequestId: f5d52f43-c0b4-425e-83ec-652fadb7abf9

For our application, we need to create task and sync to outlook and since, this will go into production, we cannot use the beta version. Can anybody please help me in saving the task.

I haven't tested with SDK. Being said that I tested with Microsoft Graph Explorer/POSTMAN but i failed to repro the issue.

@Deva-MSFT I tried with the latest SDK, but still facing the same issue.

For reference, below is the code on how I am setting up the TodoTask object:

var todoTask = new TodoTask();
todoTask.Title = "Subject";
todoTask.DueDateTime = new DateTimeTimeZone() { DateTime = dueDate.Date.ToString()};
todoTask.Status = TaskStatus.NotStarted;
todoTask.Importance = Importance.Normal;
todoTask.Body = new ItemBody
{
     Content = "Test",
     ContentType = BodyType.Text
};
todoTask.IsReminderOn = true;
todoTask.ReminderDateTime = new DateTimeTimeZone() { 
     DateTime = reminderTime.Value.ToString() };
todoTask.Extensions = new TodoTaskExtensionsCollectionPage();
todoTask.Extensions.Add(new OpenTypeExtension{
     ExtensionName = "TestProperty", 
     AdditionalData = new Dictionary<string,object>{{"MyProp","MyValue"}}});

Hi Deva

I'm experiencing the same issue with the latest SDK.

I'm reviewed the related issue you linked but it did not resolve my issue.

No matter what I pass to the SDK it always returns:
"A type named 'microsoft.toDo.todoTask' could not be resolved by the model. When a model is available, each type name must resolve to a valid type."

Is there something I'm missing?

Thanks.

Can we get some input on this please?

This is a major blocker for us as we've been moving our CRMs integration from EWS to Graph and this is holding the project up now.
Would appreciate some assistance.

Thanks.

Same here. This is a major block in our progress. We already successfully managed integration of calendar events, and assumed the todotasks would work too...

What worked for me was setting the Odatatype to nil, in my golang code:
requestBody.SetOdataType(nil)

Found the solution at https://github.com/microsoftgraph/msgraph-sdk-dotnet/issues/909#issuecomment-782212535
