Question

Why does the below transaction doesn't appear in Google Analytics?

dataLayer = [{
    'transactionId': '1234',
    'transactionAffiliation': 'TEST AFFILATION',
    'transactionTotal': 38.26,
    'transactionTax': 1.29,
    'transactionShipping': 5,
    'transactionProducts': [{
        'sku': 'DD44',
