Update packaged and now I get this on my slice

[elira1]

TS2742: The inferred type of 'usersSlice' cannot be named without a reference to '@reduxjs/toolkit/node_modules/immer/dist/internal'. This is likely not portable. A type annotation is necessary.

We'd need to see an example that reproduces this issue. Might be worth deleting node_modules and reinstalling.

On my side, I had this error message because my local version of immer was not the same than @reduxjs/toolkit one.
After upgrading it to 9.0.14, it went well.

@thibaultboursier +1 looking at yarn why immer I had a few versions installed (one was from redux toolkit, others were from other dependencies). After adding a yarn resolution for the RTK one it fixed the type error. Thanks for the idea!

Try this, next project or mono repo project, delete your node_module, package-lock.json then reinstall everything with npm i. That fixed my issue. Don't forget to restart/reload VScode for eslint to refresh.

Adding immer didn't fix my issue, and I didn't need immer to resolve it at the end.
