The main issue is in script.innerHTML="dataLayer = [ ] "; line. Actually, you are trying to concatenate string double quote "" but inside the [] array, there is also double quote"" available. So you need to change script.innerHTML= 'dataLayer = [ ]';
I have changed it and it's working now.
var script = document.createElement("script");
script.type="text/javascript";
script.innerHTML='dataLayer=[{"transactionId":"100087965","transactionTotal":1090,"transactionTax":0,"transactionShipping":0,"currencyCode":"LKR","transactionProducts":[{"sku":"ZZ48-XL","name":"White Cold Shoulder Floral Top","category":"Default Category Clothing Tops ","price":1090,"quantity":1}]}];console.log("Debug Objects:");';
document.getElementsByTagName('head')[0].appendChild(script);
