Reminder Grain etag mismatch when calling RegisterOrUpdateReminder

[rdlaitila]

when calling a reminder register or update:

public override async Task OnActivateAsync()
        {
            await RegisterOrUpdateReminder(
                nameof(SomeFunc),
                TimeSpan.FromMinutes(1),
                TimeSpan.FromMinutes(1)
            );

            await base.OnActivateAsync();
        }

orleans runtime in client integration throws:

      UpsertRow

Orleans.EntityFrameworkCore includes reminders in its test suite, not sure why we are getting this failure when integrated into another application.
