Hello @EPlaza , hi [@Jaycee\_Lewis](https://community.hubspot.com/t5/user/viewprofilepage/user-id/127074) !  
Seems like the json object is not formatted properly, try to stick with the double quotes arount keys and values (is strings) and pay attention to your commas.  
Here is the corrected partial version of your object as it should be formatted:

```lia-code-sample
{
	"properties": {
		"checkout_id": 12,
		"total": 129990,
		"products": [{
				"value1": 1,
				"value2": "value2",
				"price": 0
			},
			{
				"value1": 1389368,
				"value2": "value2",
				"price": 40000
			}
		],
		"email": "random.email@gmail.com"
	},
	"eventName": " pe21569360_order_completed",
	"email": "random.email@gmail.com"
}

```

Hope this helps you resolve your issue, also a helpful tool in those situations is a _ **json formatter** _, because it helps you with debugging the json object. I won’t suggest one here but if you do search the google you should find plenty of those.
