Error: rxfire Generic type 'AggregateQuerySnapshot<T>' requires 1 type argument(s) in angular build after npm install

Question

I'm getting a new error in Angular after a maintenance npm upgrade where no direct dependency versions changed.

ng serve produces this error and the build fails:

[ng]
[ng] Error: node_modules/rxfire/firestore/lite/interfaces.d.ts:8:29 - error TS2314: Generic type 'AggregateQuerySnapshot<T>' requires 1 type argument(s).
[ng]
[ng]  8 export type CountSnapshot = lite.AggregateQuerySnapshot<{
[ng]                                ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[ng]  9     count: lite.AggregateField<number>;
[ng]    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[ng] 10 }, any, DocumentData>;
[ng]    ~~~~~~~~~~~~~~~~~~~~~
[ng] × Failed to compile.

How can I fix this?

I already reinstalled the full project from scratch. Package dependencies match angular fire instructions:

 "dependencies": {
    "@angular/common": "^15.2.2",
    "@angular/core": "^15.2.2",
    "@angular/fire": "^7.5.0",
    "@angular/forms": "^15.2.2",
    "@angular/platform-browser": "^15.2.2",
    "@angular/platform-browser-dynamic": "^15.2.2",
    "@angular/router": "^15.2.2",
    "@angular/service-worker": "^15.2.2",
    "firebase": "^9.17.1",
    "tslib": "^2.2.0",
    "zone.js": "~0.11.4"
  },

I resolved this issue by force installing rxfire version 6.0.3

npm install [email protected]

I had to restart ng serve as well.
