Redirect didn't work anymore on Ghost 4

I tried to use redirects.json and redirects.yaml on Ghost v4.1.2, but no method worked.

All redirect URL go to 404 instead redirecting.

Redirect reference as below.

- from: /@me/
  to: /introduce/
  permanent: false
- from: /ghostorg/
  to: ''
  permanent: false

The redirects.json used to worked fine on Ghost v3 but now it didn’t work on Ghost v4.
