I foresee it because you have upgraded the redux-thunk library. In the latest version, they do not use the default export.

Check your thunk import:

import { thunk } from 'redux-thunk'

As for me, the project i'm working on uses redux-toolkit (it doesn't have the explicit redux-thunk package installed). But this solution works indeed. Thanks you @ifree92
