checkout.customer.orders_count returning 0 on order status page

[thahn]

Hey,

I noticed that the checkout.customer.orders_count parameter can return 0 as a value and I can't find out why this is happening.

I am using the following script on the order status page to push the value of checkout.customer.orders_count into the dataLayer:

<script>
	window.dataLayer = window.dataLayer || [];
	{% if checkout.customer %}
		window.dataLayer.push({
			user_properties:{
				customer_id: "{{- checkout.customer.id | json -}}",
				customer_email: {{- checkout.email | json -}},
				customer_first_name: {{- checkout.billing_address.first_name | json -}},
				customer_last_name: {{- checkout.billing_address.last_name | json -}},
				{%- if checkout.customer.phone -%}
					customer_phone: {{- checkout.customer.phone | json -}},
				{%- elsif checkout.billing_address.phone -%}
					customer_phone: {{- checkout.billing_address.phone | json -}},
				{%- else -%}
					customer_phone: {{- checkout.shipping_address.phone | json -}},
				{%- endif -%}
				customer_city: {{- checkout.billing_address.city | json -}},
				customer_zip: {{- checkout.billing_address.zip | json -}},
				customer_address_1: {{- checkout.billing_address.address1 | json -}},
				customer_address_2: {{- checkout.billing_address.address2 | json -}},
				customer_country: {{- checkout.billing_address.country | json -}},
				customer_country_code: {{- checkout.billing_address.country_code | json -}},
				customer_province: {{- checkout.billing_address.province | json -}},
				customer_province_code:  {{- checkout.billing_address.province_code | json -}},
				customer_order_count:  "{{- checkout.customer.orders_count | json -}}",
				customer_total_spent: "{{- checkout.customer.total_spent | times: 0.01 | json -}}",
				customer_tags: {{- checkout.customer.tags | json -}},
				visitor_type: "logged_in",
			}
		});
	{% else %}
		window.dataLayer.push({
			visitor_type: "guest"
		});
	{% endif %}
</script>

For some Shopify stores this script works perfectly fine and the customer_orders_count returns correct values. For other stores, the majority of values will be 0.

Does anyone have an idea what the issue is?
Thanks ✌️
