Getting error using Templater

[ottantaventi]

I'm having troubles using the Templater plugin: I'm trying to follow the instructions laid day in https://shbgm.ca/blog/obsidian/how-to-use-templater-js-scripts

I try to execute the script by first clicking:

Then clicking on "notice"

Then i get the error:

I even go into the console, but I don't know what to do here:

I even tried to switch of ALL other plugins, a part of Templater, but the behaviour is the same.

Would you please help me, make it function ?
Thanks in advance
Alexander
