Cannot read property 'appendChild' of null

[team-btg]

I have a MVC project created in Visual Studio, but when I import the alertify.js and trying the basic
alertify.log("Standard log message"); I've got this error message.

Cannot read property 'appendChild' of null at Object.setupLogContainer (alertify.js:188) at Object.notify (alertify.js:213) at Object.log (alertify.js:174) at Object.log (alertify.js:455) at assign_back (serviceentry:721)

What should I checked? I'm using the current version from here: https://alertifyjs.org/

Had the same issue, placing script inside tag has solved it for me.

Do you mean you put the entire alertify script string into a script tag? That seemed to work for me but seems really odd.

This ended up being related to script order. I had the script being fired before the binding element was rendered.
