When creating a Planner Task using the Graph API authenticated with an Azure App and not a user, if the Planner is added to a Teams Channel as a Tab, the task can not be opened in the Teams app on IOS or Android.

Use an Azure App to authenticate to Graph
Get the “planId” and “bucketId” an existing Planner linked to a channel in a
Create a new Task using those IDs

POST to https://graph.microsoft.com/v1.0/planner/tasks
{
   "planId":"[PLANID]",
   "title":"[TITLE GOES HERE]",
   "bucketId":"[BUCKETID]" 
}

In the mobile Teams app on iOS or Android, open the > Channel > More and click on the Planner tab in the channel.
Open the Task created in #2
You get an error message "Sorry. We have run into an error Please close and reload the Teams App."

The task opens fine in the actual Planner app on Android, it also opens fine in the Teams desktop app for Windows or the web version of Teams.

Hello Benjamin Morse,
Thank you for reaching out.

Regarding to your planner task issue, it seems like device problem, Not related with Graph API.
Could you please add planner task manually and see if that shows on your iOS and Android teams app.

After adding planner task manually, if the still see that teams app on your mobile device not able to open the planner task, please remove all O365 apps on device, then reinstall them.
Additionally, I would also suggest checking if there are any firewall issues blocking the tasks updates on the mobile device. Although, It might not be the case.

Hope that helps.
Thanks.

This happens on every mobile device we have tried, several Android devices and several IOS devices. Manually added tasks work fine and looking at the output of https://graph.microsoft.com/v1.0/planner/plans/[EnterPlanID]/tasks, the only differences are in the "createdBy". The one created using the Graph API using AAD App authentication looks like this:

"createdBy": {
    "application": {
        "displayName": null,
        "id": "APP ID"
    }
},

The one created in the Planner tab in the Teams channel looks like this:


"createdBy": {                                       
    "user": {                                        
        "displayName": null,                         
        "id": "My User ID" 
    },                                               
    "application": {                                 
        "displayName": null,                         
        "id": "5e3ce6c0-... Not sure what this ID is for, Teams for Windows maybe?" 
    }                                                
},

I was able to connect my Android phone to my PC using the dev mode and the Diagnostic Data Viewer and I have captured the error from Teams Mobile, it specifically says it can not read the ID of null for the user.
