April 2024 Update to C# Example Code => This user doesn't belong to a team with shared space

[Tech Dev Oldsmar]

Dropbox has given ample warnings about adapting to Teams and Shared Spaces.  However, applying these updates have been staggered and this Sunday I lost all connections to team folders in a Blazor Server .NET 8 service class.   I solved it by inverting this condition:

if (!account.RootInfo.IsTeam)

 to

if (account.RootInfo.IsTeam)

I honestly don't know why this works but at least it got the production app back online. Reference to the DropboxClient WithPathRoot(PathRoot) code is here and this is the example code in case it helps anyone:

// Fetch root namespace info from user's account info.
var account = await client.Users.GetCurrentAccountAsync();

if (!account.RootInfo.IsTeam) // CHANGE THIS to (account.RootInfo.IsTeam)
{
    Console.WriteLine("This user doesn't belong to a team with shared space.");
}
else
{
    try
    {
        // Point path root to namespace id of team space.
        client = client.WithPathRoot(new PathRoot.Root(account.RootInfo.RootNamespaceId));
        await client.Files.ListFolderAsync(path);
    }
    catch (PathRootException ex)
    {
        // Handle race condition when user switched team.
        Console.WriteLine(
            "The user's root namespace ID has changed to {0}",
            ex.ErrorResponse.AsInvalidRoot.Value);
    }
}

Here is the cleaned up code that now works after the switch-over update (early 2024) in re Teams/Shared Spaces:

public static async Task<ListFolderResult> ListFolderInTeamSpace(DropboxClient client, string path)
{
    try
    {
        var account = await client.Users.GetCurrentAccountAsync();
        return await client.Files.ListFolderAsync(path, client.WithPathRoot(new PathRoot.Root(account.RootInfo.RootNamespaceId)));
    }
    catch (PathRootException ex)
    {
        Console.WriteLine("The user's root namespace ID has changed to {0}", ex.ErrorResponse.AsInvalidRoot.Value);
        return new ListFolderResult();
    }
}

Hi @Tech Dev Oldsmar ,

Thank you for providing this information! If your account team configuration is utilizing our updated team space functionality, the expected value for account.RootInfo.IsTeam will be false, as the account will not belong to a team with a shared space.

To determine the account team configuration, you will need to check the has_distinct_member_homes and has_team_shared_dropbox values while executing the /2/team/features/get_values endpoint. For further information on the latest updated team space, please review the following link:

• API updates to better support team spaces

That said, our WithPathRoot(PathRoot) method documentation example will not work for the latest updated team space, and I have raised this to the engineering team
