How to get and fill data by date without repeats in the seeder?

[ErriourMe]

Hello. I have a seeder:

export default class extends BaseSeeder {
  public async run() {
    await CalendarUncommonDay.fetchOrCreateMany(
      ['comment', 'date'],
      [
        {
          type: CalendarUncommonDayEnum['Free day'],
          date: DateTime.fromFormat('2023-11-06', 'yyyy-MM-dd'),
          comment: 'Free day from 4 November',
        },
        {
          type: CalendarUncommonDayEnum['Free day'],
          date: DateTime.fromFormat('2024-01-01', 'yyyy-MM-dd'),
          comment: 'new year',
        },
      ]
    );
  }
}

And a model:

export default class CalendarUncommonDay extends BaseModel {
  @column({ isPrimary: true })
  public id: number;

  @column()
  public type: string;

  @column.date()
  public date: DateTime;

  @column()
  public comment: string;

  @column.dateTime({ autoCreate: true })
  public createdAt: DateTime;

  @column.dateTime({ autoCreate: true, autoUpdate: true })
  public updatedAt: DateTime;

  @column.dateTime()
  public deletedAt: DateTime;
}

The Field "date" in the table accepts dates without time. If I'm trying to fetch data by "comemnt" and "type" fields, then all is ok, the records creates only once. If I'm adding date field, the records can't be finded then and seeder creates the records twice per run. Why it happens and how to fix it?
