When using GTM dataLayer .push, a fresh object is generated rather than simply appending it to the current dataLayer

I am in the process of setting up a dataLayer for my website, but I have encountered an issue. My understanding is that Google Tag Manager dataLayer functions in a way where you have one central dataLayer object containing all the data variables. Each time you use dataLayer.push, it adds more data to this single object. However, in my case, separate objects are being created. You can view screenshots of how it looks here: https://i.stack.imgur.com/hOqJw.png

The first object is my main dataLayer; here is the code:

https://i.stack.imgur.com/jdKok.png

The fourth object is another dataLayer created using dataLayer.push, which should ideally be added to the existing one.

https://i.stack.imgur.com/WUMbF.png

Instead of having just one object, I now have two, and adding more .push methods will create even more objects.

How can I ensure that all my dataLayer.push commands add data to my main dataLayer instead of creating additional objects?

Please review and let me know if I'm overlooking something significant. I am new to this and struggling to understand why I don't end up with a single complete dataLayer object.

Answer №1

I'm a beginner in this field and I’m confused as to why my dataLayer object is not complete at the end.

That's just how dataLayer and GTM function :) Your screenshot appears to be correct. Each instance of dataLayer.push adds another object (since dataLayer is an array of objects).
