Zaraz dont pass value to facebook pixel

We send data via the zaraz API with a payload in json format.
Here is an example:

{
	"events": [
	{
		"client":
		{
			"__zarazTrack": "CompleteRegistration",
			"value": 170,
			"currency": "USD",
			"email": "[email protected]",
			"fbp": "fb.2.1696347171071.2022862165",
			"fbc": null,
			"firstName": "\u0412\u0430\u043b\u0435\u043d\u0442\u0438\u043d",
			"lastName": "\u0412\u043e\u0440\u043e\u043f\u0430\u0435\u0432"
		},
		"system":
		{
			"device":
			{
				"ip": "127.0.0.1",
				"user-agent": "Mozilla\/5.0 (Windows NT 10.0; Win64; x64; rv:120.0) Gecko\/20100101 Firefox\/120.0"
			}
		}
	}]
}

We want to pass parameters such as “value” and “email” to “Facebook Pixel” in the “CompleteRegistration” event, but they do not appear in facebook.

All other parameters are passed (fbp, fbc, user-agent, etc).
