MSGraph Planner - How to remove assignments?

Question

Hi everyone,

I'm having issues removing assignments from Planner tasks and I'm sure it's something obvious I'm doing wrong. I don't get any errors when I run the below, but it doesn't remove the assignments as per this article - plannerAssignments resource type - Microsoft Graph v1.0 | Microsoft Learn. It does remove the appliedcategories though, which makes me think it's something related to the assignments syntax.

If anyone can shine a light onto this, that would be amazing. Thanks.

Import-Module Microsoft.Graph.Planner

$ClientSecretCredential = Get-Credential -Credential "[CLIENTID]"
Connect-MgGraph -TenantId "[TENANTID" -ClientSecretCredential $ClientSecretCredential

$plannerTaskId = "[PLANNER TASKID]"

$Task = Get-MgPlannerTask -PlannerTaskId $plannerTaskId

$params = @{
	assignments = @{
		'[USERID 1]' = $null
        '[USERID 2]' = $null
		}
	appliedCategories = @{
		category3 = $false
		category1 = $false
		}
}

Update-MgPlannerTask -PlannerTaskId $plannerTaskId -BodyParameter $params -IfMatch $Task.AdditionalProperties.'@odata.etag'

Hi @Tom Weatherill ,

If you need removing assignments from Planner tasks, you need to send a delete request, look at your code, and see that you are sending an update request, which is used to update assignments.

I also did the test to remove assignments and it ran successfully, share my code below.

Import-Module Microsoft.Graph.Planner

Remove-MgPlannerTask -PlannerTaskId $plannerTaskId -IfMatch
