hi @jfgalano
GitHub is intended for Magento Open Source users to report on issues related to Open Source only.
You can report Commerce-related issues in one of two ways:
You can use the Support portal associated with your account
or
If you are a Partner reporting on behalf of a merchant, use the Partner portal.

@irajneeshgupta I recently had this problem, are you still able to look into this?

I am running Magento Enterprise 2.2.7.

The issue is that there are hardcoded block names in magento/module-google-tag-manager/view/frontend/layout/catalog_product_view.xml such as product.info.upsell. These block names are used in \Magento\GoogleTagManager\Block\ListJson::getListBlock to retrieve information, but in my case we had removed the product.info.upsell block in a theme layout file so the code broke at \Magento\GoogleTagManager\Block\ListJson::206 due to the getListBlock method returning false (because of the missing block) and there being no code that verifies whether the block actually exists or not.

HI @sjb9774 the google-tag-manager available only in EE version, We can accept only CE issues.

[snowcore]

This happens if you removed catalog.product.related or product.info.upsell block.
Reference: vendor/magento/module-google-tag-manager/view/frontend/layout/catalog_product_view.xml
Tag manager expects these blocks to be present on a product page.
There has been fixed in EE repo.

[Ohopwood]

Was there a permanent fix applied to this?
The link in @snowcore comment doesn't work anymore.

[kanhaiya5590]

@jfgalano @Ohopwood
This happens if you removed any one of these catalog.product.related or product.info.upsell or checkout.cart.crosssell or search_result_list or checkout.cart.crosssell or category.products.list block(s).
To make it work i created a patch.

Hope this will help.
