Custom webpack configuration for angular karma tests not resolving Components but works for Directives

Question

I made custom webpack config for angular karma and when starting tests, getting this message for each test with @Component decorator:

TypeError: Cannot read property 'ɵcmp' of undefined at getComponentDef (http://localhost:9876/karma_webpack/main.js:71825:14)

Tests with @Directives working without errors.

I'm adding for angular build in custom webpack config following plugin and rule with disabled aot(jitMode=true):

Package versions:

• webpack 5.36.2
• @ngtools/webpack 11.2.11

has anyone faced such a problem?
