[Client bug]: Planner CheckList .Net SDK error

[guilhermemgoncalves]

Describe the bug

I used the example on the learn site to create my request:

https://learn.microsoft.com/pt-br/graph/api/plannertaskdetails-update?view=graph-rest-1.0&tabs=csharp

I always receive the following error:

"The request is invalid:\r\nValue cannot be null.\r\nParameter name: qualifiedName"

I have tried to search for these issues and the closest thing I could find was addressed in this issue:

https://learn.microsoft.com/en-us/answers/questions/1192857/planner-task-assigned-to-user-using-graph-api

In the above case, the parameter has a corresponding class. But the checklist does not.

To Reproduce
Generate Graph Client and acquire token

public async Task<PlannerTask> InsertTarefa(string bucketId, string idPlanner, Dictionary<string, string> conteudoTask)
        {

            GraphServiceClient graphClient = CriarGraphClient(await gah.ObterTokenGraphAsync());

            var requestBody = new PlannerTask
            {
                PlanId = idPlanner,
                BucketId = bucketId,
                Title = conteudoTask["titulo"], 
                DueDateTime = DateTime.Parse(conteudoTask["dataFim"]),
                StartDateTime = DateTime.UtcNow,
                Details = new PlannerTaskDetails
                {
                    Description = conteudoTask["descricao"],
                    
                    Checklist = new PlannerChecklistItems()
                    {
                        AdditionalData = new Dictionary<string, object>
                        {
                            {
                                "95e27074-6c4a-447a-aa24-9d718a0b86fa", new
                                {
                                    OdataType = "microsoft.graph.plannerChecklistItem",
                                    Title = "Update task details",
                                    IsChecked = true
                                }
                            }
                        }
                    }
                }
            };
            try
            {
                return await graphClient.Planner.Tasks.PostAsync(requestBody);
            }
            catch (ODataError error)
            {
                Console.WriteLine(error.Error.Message);
                throw new Exception(error.Error.Message);
            }

        }

Expected behavior
Create a Task White PreBuilt Values of Checklist

Client version
SDK graphClient 5.19.0
Permissions AAD: Task.ReadAll and Task.ReadWriteAll.

We will fix the missing PlannerChecklistItem model so that the snippet can be

        var requestBody = new PlannerTask
        {
            PlanId = "idPlanner",
            BucketId = "bucketId",
            Title = "titulo",
            DueDateTime = DateTime.Parse("dataFim"),
            StartDateTime = DateTime.UtcNow,
            Details = new PlannerTaskDetails
            {
                Description = "descricao",

                Checklist = new PlannerChecklistItems()
                {
                    AdditionalData = new Dictionary<string, object>
                        {
                            {
                                "95e27074-6c4a-447a-aa24-9d718a0b86fa", new PlannerChecklistItem
                                    Title = "Update task details",
                                    IsChecked = true
                                }
                            }
                        }
                }
            }
        };

I have the same issue with the Microsoft.Graph.Models.PlannerTask object. Sending this to the Create Planner Task Endpoint gives me "The request is invalid:\r\nValue cannot be null.\r\nParameter name: qualifiedName". When commenting out the "Assignments" Dictionary, it works.

            var task = new PlannerTask
            {
                PlanId = planId,
                BucketId = bucketId,
                Title = title,
                StartDateTime = DateTime.Now,
                DueDateTime = DateTime.Now.AddHours(1),
                Assignments = new PlannerAssignments
                {
                    AdditionalData = new Dictionary<string, object>
                    {
                        {
                            "95e27074-6c4a-447a-aa24-9d718a0b86fa", new
                            {
                                OdataType = "#microsoft.graph.plannerAssignment",
                                OrderHint = " !",
                            }
                        },
                    }
                }
            };

Same with Microsoft.Graph.Models.PlannerExternalReferences and Microsoft.Graph.Models.PlannerChecklistItems in Update plannertaskdetails.

The Microsoft.Graph.Models.PlannerExternalReferences gives a different error message: "The request is invalid:\r\nAn unexpected instance annotation name 'https%3A//developer%2Emicrosoft%2Ecom/en-us/graph/graph-explorer' was found when reading from the JSON reader, In OData, Instance annotation name must start with @."

I'm having the same issue. Is the key on the dictionary simply a unique string?

`public async static Task UpdateDetailsOfTaskAddChecklist(GraphServiceClient graphClient, PlannerTask plannerTask, string[] checklistItems)
{
PlannerTaskDetails requestBody = await graphClient.Planner.Tasks[plannerTask.Id].Details.GetAsync();
string eTag = requestBody.AdditionalData["@odata.etag"].ToString();

    requestBody.PreviewType = PlannerPreviewType.Checklist;

    if (requestBody.Checklist == null)
    {
        requestBody.Checklist = new PlannerChecklistItems();
        requestBody.Checklist.AdditionalData = new Dictionary<string, object>();
    }

    foreach (var i in checklistItems)
    {
        requestBody.Checklist.AdditionalData.Add(Guid.NewGuid().ToString(),
            new
            {
                OdataType = "microsoft.graph.plannerChecklistItem",
                Title = i,
                IsChecked = false
            }
         );
    }



    var result = await graphClient.Planner.Tasks[plannerTask.Id].Details.PatchAsync(requestBody, (requestConfiguration) =>
    {
        requestConfiguration.Headers.Add("Prefer", "return=representation");
        requestConfiguration.Headers.Add("If-Match", eTag);
    });

    return result;
}`

                    }
                }
            };

Any chance this works out if you specify the type in the dictionary as

"95e27074-6c4a-447a-aa24-9d718a0b86fa", new PlannerAssignment
{
    OdataType = "#microsoft.graph.plannerAssignment",
    OrderHint = " !",
}

This worked indeed. Thank you!

Is there a similar way to solve this for the PlannerExternalReferences List?
I could not find an object named Microsoft.Graph.Models.PlannerExternalReference to solve this? I am using the Package Microsoft.Identity.Web.GraphServiceClient 2.13.1, which uses Microsoft.Graph 5.12.0 internally. I don't think I can update the Microsoft.Graph package independently from Microsoft.Identity.Web.GraphServiceClient.

var details = new PlannerTaskDetails
{
    Id = taskId,
    Description = description,
    References = new PlannerExternalReferences
    {
        AdditionalData = {
			"https://learn.microsoft.com/", new
			{
				OdataType = "#microsoft.graph.plannerExternalReference",
                Alias = "Microsoft Learn",
                Type = "Other",
			}
		},
    }
};

This will be resolved with #2095
