Возникает ошибка в импорте данных в pgsql в скрипте ruby

Есть такая таблица

CREATE TABLE public.partitioned_purchases (
    id bigint NOT NULL,
    project character varying NOT NULL,

и есть такой код импорта

require 'csv'

class ImportPurchases
  def run(file_path = nil)
    values = []
    batch_size = 1_000
    batch_number = 0
    start = Time.current.to_i
    file_path = Rails.root.join('purchase_data', 'purchases.csv') if file_path.blank?
    headers = CSV.open(file_path, 'r', &:first)
    columns = PartitionedPurchase.column_names - %w[id created_at updated_at]
    conflict_target = %w[project link_item_id]
    key_update = { conflict_target: conflict_target, columns: columns }
    CSV.foreach(file_path).each_with_index do |row, idx|
      next if idx.zero?

      values.push(row)
      next unless values.count % batch_size == 0

      batch_number += 1
      PartitionedPurchase.import(headers, values, validate: true, on_duplicate_key_update: key_update)
      values = []
      logger.info("Batch number #{batch_number} | seconds spended #{Time.current.to_i - start}")
    end
    return if values.blank?

    PartitionedPurchase.import(headers, values, validate: true, on_duplicate_key_update: key_update)
  end

  def logger
    @logger ||= Logger.new('log/import_purchases.log')
  end
end

эти воркеры выполняются в saidkiq

и при импорте возникает такая ошибка

PG::CheckViolation: ERROR:  no partition of relation "partitioned_purchases" found for row
DETAIL:  Partition key of the failing row contains (receipt_created_at) = (2023-05-03 17:11:34).


еще такая раньше выскакивала, я немного индексы подправил 

PG::InvalidColumnReference: ERROR: there is no unique or exclusion constraint matching the ON CONFLICT specification : INSERT INTO "partitioned_purchases"

Хотел спросить совета у экспертов по pg, в чем может быть дело?
