Getting KeyError: 'WINDOWSSDKDIR' while running Chromium browser source code on Windows

MAIN OBJECTIVE: I'm trying to build and run Chromium browser source code on my Windows. I want to create my own browser. The doc I'm following: https://chromium.googlesource.com/chromium/src/+/master/docs/windows_build_instructions.md

PROBLEM: I'm trying to follow every step and command as mentioned in the doc. I'm having trouble while running this command gn gen out/Default. I'm getting the following error (see the screenshot):

KeyError: 'WINDOWSSDKDIR'
ERROR at //build/config/win/visual_studio_version.gni:27:7: Script returned non-zero exit code.

Here is vs_toolchain.py: https://github.com/arkadee/demo_files/blob/master/vs_toolchain.py

I'm using the latest version of VS Code. I've tried finding the solution myself, but, there are limited resources on the internet about Chromium. Any help will be appreciated, thanks!

Looks like WindowsSdkDir env variable is missing on your computer. You should install Visual Studio (VS Code is different) and the Window SDK, though it doesn't use VC compiler or linker anymore but GN build system needs the path of Windows SDK to copy all the relevant files to the build folder. Go to command prompt and type set, do you see WindowsSdkDir env variable? If not then either the SDK is missing or the env variable has been wiped out
