Google Tag Manager error: “No HTTP response detected”

Question

I have added the Google Dynamic Re Marketing Tag to my website by use of my GTM account (test@gmail.com) successfully; it was shown with minor warnings in Google Tag Assista

Answer 1

This means clearly the code is not getting executed, could be syntax error, or extra parameters...etc. In my scenario I was sending transaction as part of Ecommerce, (ref : https://developers.google.com/analytics/devguides/collection/analyticsjs/enhanced-ecommerce )

ga('require', 'ec', 'commerce.js'); ///HTTP RESPONSE NOT DETECTED..error.
ga('require', 'ec'); ///SOLVED THE ISSUE

so on similar grounds, check the syntax!
