Module not found. Can't resolve 'assets/styles/constants'

I've wanted to add Expo in my React Native project to start it in web browser. After doing that, I try to import file 'assets/styles/constants.ts'. This is my tsconfig.json:

tsconfig.json

This is constants.ts:

constants.ts

And here I try to import this file:

DropdownAlertCustom.tsx

After that, I get this error:

error message

What am I doing wrong? And how I can fix it?
