Mailjet Vars blank array throws error

问题

$array = [
  "low_price_low_stock_goods" => []
]

In my mailjet template

   {% for item in var:low_price_low_stock_goods %}
       <tr>
           <td>{{ item.good_name }}</td>
           <td>{{ item.value }}</td>
           <td>{{ item.count }}</td>
       </tr>
   {% endfor %}

error is now No value for "var:low_price_low_stock_goods"

As I answered you on Github Ricky: it's a known issue on Mailjet's templating language side, sorry for that. To avoid it, just pass a valid object in the API call for the low_price_low_stock_goods value. This will work:

{
  item.good_name: "",
  item.value: "",
  item.count: ""
}
