Error when executing right to be forgotten in scheduled task

I'm trying to create a Sitecore scheduled task to automatically ExecuteRightToBeForgotten for contacts that haven't had any interaction with the site for a number of days.

I can get the contacts I need, but after calling ExecuteRightToBeForgotten and Submitting the changes, an error is thrown:

My xDB is up and there are Contacts that are found to be forgotten (532 in total). Is this a thing with scheduled tasks not being able to edit contacts or something?

Here's the code that's being run by the scheduled task:

public class ContactCleanupTask 
{
    private const string CleanupAfterDays = "Foundation.ContactCleanup.CleanupAfterDays";

    public void Execute(Item[] items, Sitecore.Tasks.CommandItem command, Sitecore.Tasks.ScheduleItem schedule)
    {
        Log.Info("Starting ContactCleanup task", this);

        if (!int.TryParse(Settings.GetSetting(CleanupAfterDays), out var days))
        {
            days = 420; // 14 months
        }
        var result = CleanupContacts(days);

        Log.Info($"ContactCleanup finished, executed right to be forgotten for {result} contacts.", this);
    }

    private int CleanupContacts(int days)
    {
        int numberOfForgottenContacts = 0;
        using (var client = SitecoreXConnectClientConfiguration.GetClient())
        {
            try
            {
                // Query to find contacts without any interactions after set amount of days
                var query = client.Contacts
                    .Where(contact => !contact.Interactions.Any(interaction => interaction.EndDateTime > DateTime.UtcNow.AddDays(-days)));

                // Execute query and extract contacts
                var contactCursor = query.GetBatchEnumeratorSync(50);

                while (contactCursor.MoveNext(50))
                {
                    var currentBatch = contactCursor.Current;

                    foreach (var contact in currentBatch)
                    {
                        numberOfForgottenContacts++;
                        client.ExecuteRightToBeForgotten(contact);
                    }

                }

                client.Submit();
            }
            catch (XdbExecutionException ex)
            {
                Log.Error("Xdb Error while processing contacts to forget", ex, this);
            }

            return numberOfForgottenContacts;
        }
    }
}

Note; the catch isn't hit because it's not an xDbExecutionException, but the ContactCleanupTask.cs:line 53 from the log is the client.Submit(); call

Can you help me?
