我想做一个交易，我正在使用findOneAndUpdate，我得到以下错误：“MongoServerError：Transaction numbers are only allowed on a replica set member or mongos”。我该怎么办？
app.module.ts:

imports...

@Module({
  imports: [
    ...,
    MongooseModule.forRoot(process.env.URL_DATABASE, {
      useNewUrlParser: true,
      useUnifiedTopology: true,
      retryAttempts: 2,
    }),
  ],
  controllers: [AppController],
  providers: [
    AppService,
  ],
})
export class AppModule {}

字符串
my.service.ts:

import { Connection } from "mongoose"

export class MyService {
 constructor(
    @InjectModel(User.name)
    private userModel: Model<UserDocument>,
    @InjectConnection() private readonly connection: Connection,
  ) {}
}

async delete(idPa: string): Promise<boolean> {
 let result = false;
 const session = await this.connection.startSession();

 try {
      await session.withTransaction(async () => {
        await this.userModel.findOneAndUpdate(
          { _id: idPa },
          { status: false },
          { session },
        );
      });

      result = true;
    } finally {
      await session.endSession();
    }
}

型
因此，当从控制器运行我的服务时，我得到：MongoServerError：Transaction numbers are only allowed on a replica set member or mongos.
