Cannot build angular project

From what I can tell, I followed the documentation pretty closely. The project has no errors when I run ng serve, the api calls are working fine locally. Only when I run ng build I see an error. The error I am getting is the following after triggering a build:

Error: src/app/core/graphql/graphql.module.ts:11:33 - error TS2322: Type '{ url: string; }' is not assignable to type 'string | URIFunction'.
    Type '{ url: string; }' provides no match for the signature '(operation: Operation): string'.

    11        link: httpLink.create({ uri: environment.preloginServiceUrl }), 
                                   ~~~

  node_modules/apollo-angular/http/types.d.ts:12:5
    12     uri?: string | URIFunction;
           ~~~
    The expected type comes from property 'uri' which is declared here on type 'Options'

My graphql module:

import { HttpClientModule } from '@angular/common/http';
import { APOLLO_OPTIONS } from 'apollo-angular';
import { HttpLink } from 'apollo-angular/http';
import { InMemoryCache } from '@apollo/client/core';
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { environment } from 'src/environments/environment';

export function createApolloFactory(httpLink: HttpLink) {
    return {
        link: httpLink.create({ uri: environment.preloginServiceUrl }), // HERE WE WILL PUT OUR GRAPHQL URL
        cache: new InMemoryCache(),
    };
}

@NgModule({
    imports: [BrowserModule, HttpClientModule],
    providers: [
        {
            provide: APOLLO_OPTIONS,
            useFactory: createApolloFactory,
            deps: [HttpLink],
        },
    ],
})
export class GraphQLModule {}

I tried changing around the versions of graphql/apollo packages, but still no luck -- this is the first time I'm encountering this with apollo-angular.. must be something I'm doing wrong?
