When I add AutoRepositoryTypes attribute to my DbContext the application throw an error. Why is this happening? Please see below code used and error details. Thank you

[AutoRepositoryTypes(
    typeof(IRepository<>),
    typeof(IRepository<,>),
    typeof(MyAppRepositoryBase<>),
    typeof(MyAppRepositoryBase<,>)
    )]
public class MyAppDbContext : AbpZeroDbContext<Tenant, Role, User, MyAppDbContext>, IAbpPersistedGrantDbContext

    The error messages are pretty clear.

    MyAppRepositoryBase does not have a public default constructor and could not be instantiated. Constructor on MyAppRepositoryBase not found.

    public class MyAppRepositoryBase<TEntity, TPrimaryKey> : EfCoreRepositoryBase<MyAppDbContext, TEntity, TPrimaryKey>
    where TEntity : class, IEntity<TPrimaryKey>
{
    public MyAppRepositoryBase(IDbContextProvider<MyAppDbContext> dbContextProvider)
        : base(dbContextProvider)
    {
    }
}

public class MyAppRepositoryBase<TEntity> : MyAppRepositoryBase<TEntity, int>
    where TEntity : class, IEntity<int>
{
    public MyAppRepositoryBase(IDbContextProvider<MyAppDbContext> dbContextProvider)
        : base(dbContextProvider)
    {
    }
}
