Error when scaffolding endpoints with database context placed in a separate project

My repo at https://github.com/suugbut/CodegenBug provides some batch files to generate the solution and many more. Here I just pasted the problem description from it.
***
To illustrate the problem, I make 4 projects as follows:

- `Model` project with one entity model `User.cs`
```csharp
public class User
{
public int Id { get; set; }
public string Name { get; set; } = default!;
}
```

- `Context` project with one database context `AppDbContext.cs`
```csharp
public class AppDbContext : DbContext
{
public AppDbContext(DbContextOptions options) : base(options) { }
public DbSet Users => Set();
}
```
- `MigrationForSqlite` project with a trivial class `Empty.cs`
```csharp
public class Empty { }
```
This project is used to keep migration files generated by ef tool for specific db provider (in this case for sqlite).

- `Api` project with `Program.cs`
```csharp
var builder = WebApplication.CreateBuilder(args);

builder.Services.AddDbContext(dcob =>
{
dcob.UseSqlite("DataSource=Test.db",
sdcob => sdcob.MigrationsAssembly("MigrationForSqlite"));
});

var app = builder.Build();

app.MapGet("/", () => "Hello World");

app.Run();
```

I successfully did the following:

- migration: `dotnet ef migrations add Initializaiton -s Api -p MigrationForSqlite`
- applying migration: `dotnet ef database update -s Api`
- running api server: `dotnet run --project Api --launch-profile https`
- testing endpoint by navigating to `https://localhost:7255` that produces `Hello World`

After shutting the server down, I attempted to scaffold endpoints for `User` model with the following batch file but I failed.
```
dotnet aspnet-codegenerator minimalapi ^
-p Api ^
-e UserEndpoints ^
-m Model.User ^
-dc Context.AppDbContext ^
-outDir Endpoints ^
-dbProvider sqlite
```

The error messages are:
```

Minimal hosting scenario!
