Type '{ ... }' does not satisfy the constraint 'AsyncThunkConfig'

[jonathan-rosa]

Possibly related to #3758

Using @reduxjs/toolkit in my TypeScript project leads to these type errors related to AsyncThunkConfig.

Initially tsc was latest version, so I downgraded to 5.5.4 as it is defined in package.json and it does not help. How am I supposed to be using TypeScript with redux-toolkit?

your type checker shouldn't be checking our type definitions - turn skipLibCheck on.
