I've configured a custom event on Google Tag Manager to send data about my product to Google Analytics using "datalayer", but when I send hit the event it's label is shown as [object Object] into analytics reports.
How do I get all properties of the product there?
Example of data that I'm pushing:
{
'event': 'test',
'action': 'add',
'product': {
'id': 32,
'name': 'Product 1',
'price': 99.99
}
}
