Cannot update a ToDo item using MsGraph

David Craggs 0

I am trying to update a ToDo item using MsGraph.

I can create one using this URL

'me/todo/lists/TASKLISTID==/tasks

Json sent is

{"title":"Test new","dueDateTime":{"dateTime":"2024-07-17T00:00:00.000Z","timeZone":"UTC"}}

Works fine

But updating using this url with the same json fails

me/todo/lists/TASKLISTID/tasks/TASKID

Fails with a 404 and this message

{"error":{"code":"UnknownError","message":"","innerError":{"date":"2024-07-17T14:33:22","request-id":"a82fbb85-aac4-4988-b350-131d57a5c92e","client-request-id":"a82fbb85-aac4-4988-b350-131d57a5c92e"}}}

TASKID is correct

Note TASLKLISTID and TASKID are replaced with real values.

Getting the same result when I try it in MS Graph Explorer

Any ideas?

BTW - ChatGPT took me through all the obvious stuff!

Please post the actual HTTP request you're sending. Creating a task uses POST and a formal task definition. An update is a PATCH and requires only the fields you're changing. Given a 404 you're either using the wrong IDs or the wrong verb I'd wager. Posting the actual HTTP requests would help clarify that. Refer to the docs for an example request for update and try to see if that works for your new task.

OK - using MS Graph Explorer I create a ToDo Item

Body is

{ "title": "Task created from Microsoft Graph Explorer" }

I then take the ID returned AAMkADI3MTM5MWE5LWIzN2EtNDg4Yy1hMjRlLTZhZThjNTMxNjU5MABGAAAAAACGbvdsrReMR75E7eEW_oAPBwDqjrbjb9SHQroeDqRHKUizAAAAAAETAABuVJRA-H5kQ7K-B23PBH-3AAa8qYUcAAA=

And append it to the URL, with a forward slash

This should turn it into an update

But this happens

{ "error": { "code": "UnknownError", "message": "", "innerError": { "date": "2024-07-18T06:27:03", "request-id": "79272cb2-76ff-4c46-a40c-0422c24db977", "client-request-id": "8d9ee9bb-0b09-c148-06c7-18eff78da151" } } }

What am I missing?

Just spotted

Possible error found in URL near: -H5kQ7K-B23PBH-3AAa8qYUcAAA=

See my other comment on your answer. I can get it to work just fine in GE but the PATCH url in GE is wrong for updating a task. The URL should be https://graph.microsoft.com/v1.0/me/todo/lists/{tasklist-id}/tasks/{task-id}. It is missing the subresource/id part. Adding that in correctly updates the task.

Changed the forward slash to a ? before the task ID and it worked

Sorry - No it didn't.

No that doesn't work - just creates a new task :-(

Can anyone create a ToDo item in MS Graph Explorer?

In your update call you're using POST as the verb. In GE change the verb to PATCH and try your request again.
