I’m trying to create a new table that has 2 foreign keys into another table. I’ve done this before and didn’t have any trouble, but now when I try to create the migration, I’m getting the following error:

$ dotnet ef migrations add RequestLedger
Build started…
Build succeeded.
Unable to create a ‘DbContext’ of type ”. The exception ‘Unable to determine the relationship represented by navigation ‘RequestLedger.NewStatus’ of type ‘RequestStatusType’. Either manually configure the relationship, or ignore this property using the ‘[NotMapped]’ attribute or by using ‘EntityTypeBuilder.Ignore’ in ‘OnModelCreating’.’ was thrown while attempting to create an instance. For the different patterns supported at design time, see https://go.microsoft.com/fwlink/?linkid=851728

The relevant parts of my cs files are:

RequestLedger.cs:
public long OldStatusId { get; set; }

public long NewStatusId { get; set; }

public virtual RequestStatusType OldStatus { get; set; } = null!;
public virtual RequestStatusType NewStatus { get; set; } = null!;

RequestLedgerEntityTypeConfiguration.cs:
       builder.HasOne(d => d.OldStatus)
            .WithMany(p => p.OldRequestLedgers)
            .HasForeignKey(d => d.OldStatusId)
            .OnDelete(DeleteBehavior.Restrict);
        builder.HasOne(d => d.NewStatus)
            .WithMany(p => p.NewRequestLedgers)
            .HasForeignKey(d => d.NewStatusId)
            .OnDelete(DeleteBehavior.Restrict);

RequestStatusType.cs:
        OldRequestLedgers = new HashSet<RequestLedger>();
        NewRequestLedgers = new HashSet<RequestLedger>();

    public virtual ICollection<RequestLedger> OldRequestLedgers { get; set; }
    public virtual ICollection<RequestLedger> NewRequestLedgers { get; set; }

What am I missing here?
