I have upgraded my Angular application from 12 to 13 version. And I started getting this error during unit test run.
Chrome Headless 94.0.4606.61 (Windows 10) AppComponent should create the app FAILED
TypeError: Cannot read properties of undefined (reading 'match')

I tried this solution but it didn't work.
manually remove package-lock.json
manually remove folder node_modules
npm install
Do you have any ideas how to fix it? Is it connected to Angular version upgrade?
I found the solution in this answer https://stackoverflow.com/a/68797111/3387259
I have changed commonjs to es2020 in tsconfig.json and also added "moduleResolution": "node".
For me, I was using a config.env and forgot to put "ATLAS_URI=" before my connection url. Adding "ATLAS_URI=" to my config.env fixed my TypeError.
