[davidmarjanidze]

Temporary solution is to npm i [email protected], but I don't know the side effects of this solution.

I have the same problem, with a brand new application. I use Angular Cli version 16.2.4 and Angular 16.2.7. After adding AngularFire (version 7.6.1) with ng add @angular/fire, I get the error:

Error: node_modules/rxfire/firestore/lite/interfaces.d.ts:8:29 - error TS2314: Generic type 'AggregateQuerySnapshot<T>' requires 1 type argument(s).

 8 export type CountSnapshot = lite.AggregateQuerySnapshot<{

 9     count: lite.AggregateField<number>;
   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
10 }, any, DocumentData>;
