How to add users to a group column through PowerApps to SharePoint List.

Question

I am making a Ride Sharing App were users can schedule (create), join, and leave rides. Information regarding each scheduled ride is stored in a SharePoint list. Each record has a Members column which stores all users who have joined that particular ride. When a user joins, I need to update the current Table of users by adding the current user. I have attached my solution as of now.

I am getting two errors: 'Invalid Argument Type. Expected Table value, but of different schema.' and 'Missing column. Your formula is missing a column Claims of type Text.' I am not sure the proper solution.

I found my current solution here: https://powerusers.microsoft.com/t5/Building-Power-Apps/Add-Person-to-the-Multi-Select-Person-Column-in-Sharepoint-from/td-p/2246551

Patch(
    RideShareRevert,
    RideGallery.Selected,
    {
        Members: Ungroup(
            Table(
                {
                    Items: RideGallery.Selected.Members
                },
                {
                    Items: [
                        {
                            Claims: "i:0#.f|membership|"&Lower(User().Email),
                            DisplayName: "",
                            Email: User().Email,
                            JobTitle: "",
                            Picture: ""
                        }
                    ]
                }
            ),
            "Items"
        )
    }
)

I added Department: "" to the user object and it worked.

Answer 2

Hi @Ayden Franklin ,

According to your description, this cannot be achieved directly in SharePoint and is more related to Power Apps. As a SharePoint engineer, I am not good at Power Apps. And unfortunately, Power Apps is currently not supported in the Q&A forum. In order to better solve the issue, we suggest you start a new discussion via the Power Apps Community so that you can get dedicated support on this issue.

Thanks for your understanding!
