Problem creating MS Planner flow

Hey All


I am trying to create a Flow that creates a Planner task, then updates that Planner task, when a JSON webhook is received.


I can receive the webhook fine

I can then look up the user to assign the Planner task to fine via the office354 lookup

I can create the Planner task fine however,

When i try to update the task using the ID value from the "creatae a task" step, i get a 404 error when testing.  This is what the setup looks like:  Here is the Inputs in the test:


and here is the 404 error:

  "error": {
    "message""The requested item is not found.",
    "innerError": {


Any ideas why the task ID would not be found in the Update Task lookup?

Re: Problem creating MS Planner flow

Hi @nydamon,


Could you please share a screenshot of your flow's configuration?

Do you add a "Update a task" action within your flow?


I have made a test and the issue is confirmed on my side. The user @Miller1 has faced similar issue with you, please check the following thread:


You could consider take a try to add a "Delay" action between the "Create a task" action and the "Update a task" action as that mentioned within above thread I provided. I have made a test on my side, please take a try with the following workaround:8.JPG

Within Delay action, Count set to 30 and Unit set to Second.


The flow works successfully as below:9.JPG
