window.document not defined

[NN-Tobbe]

In function googletagmanager(id,datalayer), setting window = this causes window.document to be undefined. This makes calling d.getElementByTagName cause an exception.

I fixed this by removing window = this, but I am not sure what problems this might cause. Why is windows set to this at all?

I have the same issue, I'm getting:

Uncaught TypeError: d.getElementsByTagName is not a function
