Import errors

[Dodgo1]

A lot of import errors are appearing (23 to be axact):

ERROR in ./node_modules/@remotelock/react-week-scheduler/index.mjs 34:0-45
Module not found: Error: Can't resolve 'date-fns/is_same_day' in '/mnt/c/Users/.../scheduler-manager/myapp/node_modules/@remotelock/react-week-scheduler'
Did you mean 'index.js'?
BREAKING CHANGE: The request 'date-fns/is_same_day' failed to resolve only because it was resolved as fully specified
(probably because the origin is strict EcmaScript Module, e. g. a module with javascript mimetype, a '.mjs' file, or a '.js' file where the package.json contains '"type": "module"').
The extension in the request is mandatory for it to be fully specified.
Add the extension to the request.

I solve this with
import { classes, TimeGridScheduler } from '@remotelock/react-week-scheduler/index.js';
