Not operator does not work on typeorm

Question

I am using typeorm in my Ode app and mongodb database. I have only one collection called "users" and have a route to get all users except me. So, here’s my code:

const foundUsers = await this.ormRepository.find({
      skip: parseInt(page) - 1,
      take: 2,
      order: {
        created_at: 'DESC',
      },
      where: { userProviderId: Not(userProviderId) },
    });

The problem is that ** foundUsers ** comes empty after using the ** Not** operator. If I remove the last line (where: {userProviderId: Not(userProviderId)},) everything works normally. But I want to filter the results by deleting a single search user. This is my user template:

  @Entity('users')
    class User {
      @ObjectIdColumn()
      @Exclude()
      id: ObjectID;
    
      @PrimaryColumn()
      userProviderId: string;
    
      @Column()
      name: string;
    
      @Column()
      avatar: string;
    
      @Column()
      birthDate: Date; 
      ...

So someone knows what’s going on?
