How to fix this Build error for Chromium browser in Windows?

Question

I've built the Chromium browser on my Windows from its official source code by following this documentation.

I made some changes and executed my first build and ran into some errors.

The error are as follows:

THE ERROR ON EVERY BUILD:

I am completely a newbie at this and this is my first time working on Visual Studio(v. 2019). How can I get rid of these errors? Any help would be appreciated!!
