Typescript error when iniatilising data source

[dan-cooke]

I am encountering the following error when attempting to follow the documentation

Argument of type 'Collection<Profile | UpdateQuery<Profile>>' is not assignable to parameter of type 'Collection<Profile>'.
  Types of property 'aggregate' are incompatible.

Here is my ApolloServer iniatilisation

 const client = await connectToDb();

  const schema = makeExecutableSchema({
    typeDefs: [DIRECTIVES, typeDefs],
    resolvers,
  });
  const apolloServer = new ApolloServer({
    schema,
    introspection: true,
    formatError: (error) => {
      console.error(error);
      return error;
    },
    playground: {
      endpoint: `/dev/graphql`,
    },
    dataSources: () => ({
      profiles: new Profiles(client.db().collection(`profiles`)),
    }),
  });

The line that throws the error is

 profiles: new Profiles(client.db().collection(`profiles`)),

My Profiles data source looks as follows:

import { Profile } from 'generated/mongodbTypes'
export default class Profiles extends MongoDataSource<Profile, any> { }

I am importing the following Profile type generated from my GraphQL schema by Graphql codegen

export type Profile = {
  __typename?: 'Profile';
  _id: Scalars['ObjectID'];
  user_id: Scalars['String'];
  portfolios?: Maybe<Array<Portfolio>>;
};

The weird thing is this worked on my other project before switching over to a fresh project - same code from what I can tell.

Edit:

I forgot to post versions, apologies

apollo-datasource-mongodb 0.3.0
node: 15.11.0
typescript: 4.2.3

Was it the same version of this lib in the other project?

Types of property 'aggregate' are incompatible.

So there are two Collection.aggregates, and their types are different?

Sorry, I haven't learned typescript yet, so I won't be much help, but happy to merge a PR if someone fixes this ☺️

@lorensr thanks for the reply!

Both projects are using the exact same version. I have just disabled ts checking for this line while I wait for a fix.

@dan-cooke can you post which versions of @types/mongodb do you have from your yarn.lock or package-lock.json?

[dan-cooke]

@9at8 resolved 0.3.0 for both projects

I updated my original post with Typescript and node versions as well! thanks

I have the same error and it's caused by mongodb having released its own types that conflict with those from @type/mongodb

Argument of type
 'import("[...]/node_modules/mongodb/mongodb").Collection<import("[...]/src/generated/schema").ActorDbObject>'
 is not assignable to parameter of type 
 'import("[...]/node_modules/apollo-datasource-mongodb/node_modules/@types/mongodb/index").Collection<import("[...]/src/generated/schema").ActorDbObject>'
