Cannot create webpack.config.js via webpack-cli

I cannot create webpack.config.js via webpack-cli.

I created package.json file using command yarn init

Then I installed webpack with command yarn add webpack webpack-cli @webpack-cli/init webpack-dev-server --dev Package.json file now looks like this:

{
    "name": "app",
    "version": "1.0.0",
    "main": "index.js",
    "license": "MIT",
    "devDependencies": {
        "@webpack-cli/init": "^1.1.3",
        "webpack": "^5.33.2",
        "webpack-cli": "^4.6.0",
        "webpack-dev-server": "^3.11.2"
    }
}

Now I try to initialize webpack.conf.js file with command yarn webpack-cli init but the result is:

yarn run v1.22.5  
$ /app/node_modules/.bin/webpack-cli init  
[webpack-cli] No commands found to run  
error Command failed with exit code 2.

The command init is not available:

What am I doing wrong? Previously it worked on the same docker image (node:15.3.0-buster)
