Turn Layers off In ArcGIS Pro using Arcpy

Business_IntelligenceSoftware

I have a python script that should  turn off all layers in a ArcGIS Pro project. But when I run it, the following error pops up:

File "<string>", line 2, in <module>
IndexError: list index out of range

Here is the python code I am using.

Anyone know what I am doing wrong or missing?

The simplest answer would be that the map "Name of map" doesn't exist in your project. I don't think you have to specify a map name, or you can use wildcards, if you don't always know the name.
