Unable to add Teams/SharePoint file attachment in a task to ' Tasks by Planner and To Do '

Question

I have a fully built API, that creates tasks into MS Teams "Tasks by Planner and To Do".

MS actual graph API used POST https://graph.microsoft.com/v1.0/planner/tasks

Sample API:

{
    
  "routeId": "7fcxxxxx-xxxx-xxxx-xxxx-5d35838xxxxx",
  "userId": "77cxxxxx-xxxx-xxxx-xxxx-5f09858xxxxx",
  "tenantId": "dcdxxxxx-xxxx-xxxx-xxxx-31002a1xxxxx",   
  "title": "Task: Add you task title",
  "hospitalAssignment": null,   
  "percentComplete": 0, 
  "createdTimestamp": "2021-04-20T01:51:49Z",   
  "startDateTimestamp": "2021-04-20T18:10:15Z", 
  "dueDate": "2021-11-20T11:47:33.000Z",    
  "Notes": "Add some useful notes here",    

  "checklistItems": [   
    {   
      "title": "itema"  
    },  
    {   
      "title": "itemb"  
    }   
  ],

  "attachments": [  
    {   
      "url": "https://www.google.com",  
      "alias": "link"   
    },
    {   
      "url": "https://teams.microsoft.com/file/....",   
      "alias": "Test Document 1"    
    },
    {   
      "url": "https://random.sharepoint.com/sites/...",
      "alias": "Test Document 2"    
    },  
  ],

  "comments": "null,",  
  "priority": null  
}

Hitting the above API creates a task in the planner as seen below

So, here is an issue - when I try to click on link it took me to the browser and opens up google which is fine. Now, when I click on Test Document 1 or Test Document 2 it throws an unknown error and Sorry, something went wrong respectively.

After that, I created the task manually and adding the attachments from Add Attachment and paste the links to the file there, then click the files works and opens up the documents.

Can you please add the full details of the API that you call and the complete ( redacted) sample of the body. currently it is not clear which API or Version you call or wether it is an POST or a PATCH — Jos Verlinde
Can you also clarify how you aquire the Teams/SPO file URLs ? and weather or not the file is shared with the owner of the task — Jos Verlinde
Also see this reference to (a Flow)[powerusers.microsoft.com/t5/Power-Automate-Community-Blog/… that crates a Sharing-Link to a SPO hosted document before adding it as a Task Attachment; — Jos Verlinde

Assuming you are referring to adding / updating the Planner Task Details for a PlannerTask;

there is a sample provided of adding (PATCH) a pptx file using a 'teams path' as you referred to it.
Note that the path must be (url)encoded.

Tasks - plannerTaskDetail < references

https://docs.microsoft.com/en-us/graph/api/resources/plannerexternalreferences?view=graph-rest-1.0

{
  "https%3A//contoso%2Esharepoint%2Ecom/teams/agile/documents/AnnualReport%2Epptx":
  {
    "@odata.type": "microsoft.graph.externalReference", // required in PATCH requests to edit the references on a task
    "alias": "Agile Team Annual Report",
    "lastModifiedBy": {
      "user": {
        "id": "ebf3b108-5234-4e22-b93d-656d7dae5874"
      }
    },
    "lastModifiedDateTime": "2015-09-21T17:45:12.039Z",
    "previewPriority": "0009005756397228702",
    "type": "PowerPoint"
  }
}
