  let violations = [];
  const source = options.sourceInfo.source;
  const severity = source === ecomValidations.Source.CART ? ecomValidations.Severity.ERROR : ecomValidations.Severity.ERROR;

  const validItemIds = ['39791f1e-9d2d-bd67-24f3-d6e179ee0b6e', '0b91f1b3-221e-ae04-9cda-4dc9a33e8b33'];
  const minimumTotalQuantity = 8;

  const validLineItems = options.validationInfo.lineItems.filter(lineItem => validItemIds.includes(lineItem.catalogReference?.catalogItemId));
  const validQuantitySum = validLineItems.reduce((partialSum, lineItem) => partialSum + lineItem.quantity, 0);
