Error en Shopify flows

[saantiago]

Tengo un flow que debe crear una fila y lo tengo configurado de la siguiente manera:

{{order.name}}, {{order.customer.displayName}},{% for lineItems_item in order.lineItems %}{{lineItems_item.name}} | {% endfor %},{% for fulfillmentOrders_item in order.fulfillmentOrders %}{% for lineItems_item in fulfillmentOrders_item.lineItems %}{{lineItems_item.image.url}} | {% endfor %}{% endfor %},{% for lineItems_item in order.lineItems %}
{{lineItems_item.vendor}} |
{% endfor %},{% assign total_cost = 0 %}
{% for lineItem in order.lineItems %}
{% assign total_cost = total_cost | plus: lineItem.variant.inventoryItem.unitCost.amount %}
{% endfor %}
{{ total_cost }},{% for fulfillmentOrders_item in order.fulfillmentOrders %}{{fulfillmentOrders_item.order.totalShippingPriceSet.presentmentMoney.amount}} | {% endfor %},{{order.billingAddress.phone}},{% for paymentGatewayNames_item in order.paymentGatewayNames %}{{paymentGatewayNames_item}}{% endfor %},{{order.createdAt}},{% for fulfillmentOrders_item in order.fulfillmentOrders %}
{{fulfillmentOrders_item.order.currentSubtotalPriceSet.presentmentMoney.amount}}
{% endfor %},{% for fulfillmentOrders_item in order.fulfillmentOrders %}{{fulfillmentOrders_item.order.totalShippingPriceSet.presentmentMoney.amount}} {% endfor %},{{order.displayAddress.address1}} {{order.billingAddress.address2}} | {{order.billingAddress.city}}

Recientemente me apareció un error que dice: 

"lineItem" es inválido Reemplaza esta variable.

¿Saben cómo podría resolverlo?

Esto fue causado por un error en la forma en que Flow interpreta Liquid (específicamente "assign") que ya se resolvió.
