I have UserEntity:

public record UserEntity
{
    public int Id { get; set; }

    public string Username { get; set; }
    public string FirstName { get; set; }
    public string? LastName { get; set; }

    public string Email { get; set; }
    public string PasswordHash { get; set; }

    public Roles[] Roles { get; set; }
    
    public SchoolEntity? School { get; set; }
    public int? SchoolId { get; set; }
    
    public DateTime DateOfCreating { get; set; }
    public IEnumerable<ExamOptionEntity>? ExamOptionsCreated { get; set; }
}

And SchoolEntity:

public record SchoolEntity
{
    public int Id { get; set; }
    
    public UserEntity Author { get; set; }
    public int AuthorId { get; set; }
    
    public IEnumerable<UserEntity> Students { get; set; }
    public string Link { get; set; }
    
    public PageEntity Page { get; set; }
    public int PageId { get; set; }
    
    public Subjects Subject { get; set; }
    public DateTime DateOfCreating { get; set; }
}

I need to create relationship, because School has Author and Students.
Here are fluent configuration methods:

public void Configure(EntityTypeBuilder<UserEntity> builder)
    {
        builder.HasKey(x => x.Id);
        builder.Property(x => x.Id).ValueGeneratedOnAdd();
        
        builder.HasOne(x => x.School)
            .WithOne(x => x.Author)
            .HasPrincipalKey<UserEntity>(x => x.Id)
            .HasForeignKey<SchoolEntity>(x => x.AuthorId);
    }

And

    public void Configure(EntityTypeBuilder<SchoolEntity> builder)
    {
        builder.HasKey(x => x.Id);
        builder.Property(x => x.Id).ValueGeneratedOnAdd();

        builder.HasMany(x => x.Students)
            .WithOne(x => x.School)
            .HasForeignKey(x => x.SchoolId)
            .HasPrincipalKey(x => x.Id);
    }

Finally I cached exception: "Cannot create a relationship between \u0027SchoolEntity.Students\u0027 and \u0027UserEntity.School\u0027 because a relationship already exists between \u0027UserEntity.School\u0027 and \u0027SchoolEntity.Author\u0027. Navigations can only participate in a single relationship. If you want to override an existing relationship call \u0027Ignore\u0027 on the navigation \u0027UserEntity.School\u0027 first in \u0027OnModelCreating\u0027." when I ran the application.
What could be the problem?
