Build CEF (Chormium) from Source Code error - chromium

Question

I am following the steps to make a build of Chromium from the source code:
https://chromium.googlesource.com/chromium/src/+/master/docs/windows_build_instructions.md#Install
But when I am at try to "fetch chromium"
I get the error:

The official documentation on how to build CEF (which also builds Chromium) can be found here:
https://bitbucket.org/chromiumembedded/cef/wiki/MasterBuildQuickStart.md
https://bitbucket.org/chromiumembedded/cef/wiki/BranchesAndBuilding.md
To give you a small idea of what you require:
Windows 7 or newer, 64-bit OS.
Visual Studio VS2017 15.3.2+ installed in the default location.
Windows 10.0.15063.468 SDK installed in the default location. You must install this exact SDK version to avoid build issues.
At least 8GB of RAM and 40GB of free disk space.
I recommend at least 16GB of RAM, 100 GB disk space (fast SSD), and at least a 4-core CPU. It will still take many hours to build CEF.
