I have created a Teams Service Definition with a Planner Plan and want to add it to a Teams tab. 

I am getting one of the errors below and want to know how to resolve it?

• The Planner was not added
• To view or edit this subscription, including a task in it, you must ask a member to add you to the membership list of this subscription
• Error accessing Resource

What checks do I need to make to get the Planner to be displayed

Microsoft do not support adding configured Planner tabs to Teams, the setup we provide is subject to failure if Microsoft make changes to the Tab configuration options.

Configure the built-in tab types in Microsoft Teams - Microsoft Graph | Microsoft Learn 

The Planner was not added

Causes

• The Planner has not been configured in ProvisionPoint
• The Tab configuration is incorrect

Resolutions

1. Check the Planner tab in the Service Definition
   1. If there are none there is nothing to add. Add a Planner setup, click Done and ensure the Service Definition is saved
      
2. Check you are using the latest setup in {} in the tab configuration
   

To view or edit this subscription, including a task in it, you must ask a member to add you to the membership list of this subscription

Causes

The requestor or person opening the Planner is not a member of the Team.

If ProvisionPoint uses custom columns to define Owners and Members, the setup may not be applying the correct permissions

Resolutions

Check the Form Columns to ensure that any Owner or Member columns have the 'Use for associated members' set to Yes

The Wrong Planner is Displayed

Causes

The Tab configuration in ProvisionPoint has not been updated to choose the alternative Planner

Resolutions

1. Check there are multiple Planners saved
2. Check the tab setup for each Planner
   1. To add the first Planner the tag {PlannerId} should be used
   2. To add the second planner the tag {PlannerId[1]} should be used in entityId and contentUrl
