Answer 1

Walking around that issue I finded solution:
1. this problem occurs when there are multiple versions of scheduler in the project
2. for check this use npm list scheduler, or yarn why scheduler(more info here and here )
3. if you have several versions of scheduler check link above or
- use with npm this
- use with yarn like this:

"resolutions": {
    "scheduler": "0.15.0"
  }

4. in any case after each manipulation with scheduler ALWAYS reload you react app (eg npm start)
