Having trouble with a tslint error in Typescript when creating a reducer

I encountered an error while working with a simple reducer in ngRx, specifically with the on() method.

In addition, I came across some errors in the reducer_creator.d.ts file:

Moreover, here are the versions of ngRx and TypeScript listed in my package.json:

"@ngrx/effects": "^11.0.1",
"@ngrx/store": "^11.0.1",
"@ngrx/store-devtools": "^11.0.1",
"typescript": "~3.1.6"

Does anyone have any suggestions on how to resolve this issue?
