Further, Here is my package.json ngrx and typescript versions:

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

Any suggestions to fix this issue?

Solution

  • NgRx v11 expects TypeScript 4 to be used. https://ngrx.io/guide/migration/v11
