Hello!
When I try to add unpacked folder to Chrome I get a error.

File
~/Downloads/reactjs-chrome-extension-master
Error
Manifest file is missing or unreadable
Could not load manifest.

I found this during your YouTube video tutorial repeating.
I thought it was a mistake.
But I also tried to add your GitHub folder after "yarn run build" - the same.

I'm developing a React project using Webpack configuration and noticed that image files are not being copied to the dist folder. I've tried various configurations with Webpack but still couldn't find a solution.

Edit:

Solved, I installed the file-loader and wrote this in web.common.js:

{
                test: /\.(png|svg|jpg|jpeg|gif)$/i,
                use: {
                    loader: "file-loader",
                    options:{
                        name: "[name].[ext]"
                    }
                }
 }
