Entity Framework Core One-One Self Referencing Relationship fails

When building the migration I get the following error:

Unable to determine the relationship represented by navigation property 'Location.NorthLocation' of type 'Location'. Either manually configure the relationship, or ignore this property from the model.

The Location entity:

public class Location
{
    public Guid Id { get; set; }

    public DateTime CreatedWhen { get; set; }
    public string CreatedBy { get; set; }
    public DateTime ModifiedWhen { get; set; }
    public string ModifiedBy { get; set; }

    public Guid? NorthLocationId { get; set; }
    public virtual Location NorthLocation { get; set; }

    public Guid? SouthLocationId { get; set; }
    public virtual Location SouthLocation { get; set; }

    public Guid? EastLocationId { get; set; }
    public virtual Location EastLocation { get; set; }

    public Guid? WestLocationId { get; set; }
    public virtual Location WestLocation { get; set; }

}

The type configuration:

public class MyContext : DbContext
{
    public MyContext(DbContextOptions<MyContext> options) : base(options)
    {
    }

    public DbSet<Location> Locations { get; set; }

    protected override void OnModelCreating(ModelBuilder builder)
    {
        base.OnModelCreating(builder);

        builder.Entity<T>().HasKey("Id");
        builder.Entity<T>().Property("Id").ValueGeneratedOnAdd();
        builder.Entity<T>().Property("CreatedWhen").HasDefaultValueSql("GETDATE()").ValueGeneratedOnAdd();
        builder.Entity<T>().Property("ModifiedWhen").IsRequired();
        builder.Entity<T>().Property("CreatedBy").HasMaxLength(50).IsRequired();
        builder.Entity<T>().Property("ModifiedBy").HasMaxLength(50).IsRequired();

        // Locations
        builder.Entity<Location>().HasOne(x => x.NorthLocation).WithOne(x => x.SouthLocation).HasForeignKey(typeof(Location), "NorthLocationId").OnDelete(DeleteBehavior.SetNull);
        builder.Entity<Location>().HasOne(x => x.SouthLocation).WithOne(x => x.NorthLocation).HasForeignKey(typeof(Location), "SouthLocationId").OnDelete(DeleteBehavior.SetNull);
        builder.Entity<Location>().HasOne(x => x.EastLocation).WithOne(x => x.WestLocation).HasForeignKey(typeof(Location), "EastLocationId").OnDelete(DeleteBehavior.SetNull);
        builder.Entity<Location>().HasOne(x => x.WestLocation).WithOne(x => x.EastLocation).HasForeignKey(typeof(Location), "WestLocationId").OnDelete(DeleteBehavior.SetNull);
    }

}

My goal is to have a Location entity that self-references it's own neighbours to the north/south/east/west.

Can anyone suggest why I might be getting this error?
