We are currently working with a MongoDB database that uses string IDs instead of the typical 12 bytes or 24 hex format. These IDs were generated by MeteorJS.
As we develop a GraphQL layer using apollo server, we encountered an issue when trying to load data using apollo-datasource-mongodb and calling the findOneById method. The error message received was:
Error: Argument passed in must be a single String of 12 bytes or a string of 24 hex characters
at new ObjectID (/app/node_modules/bson/lib/bson/objectid.js:59:11)
at Function.ObjectID (/app/node_modules/bson/lib/bson/objectid.js:40:43)

/app/node_modules/bson/lib/bson/objectid.js:59
This error occurs because the module is attempting to transform our string ID into a MongoDB ObjectId, which is not compatible with our current ID format.
Upon reviewing the apollo-datasource-mongodb repository, it appears that it does have the capability to handle string IDs:
findOneById(
id: ObjectId | string,
options?: Options
): Promise<TData | null | undefined>
Source: https://github.com/GraphQLGuide/apollo-datasource-mongodb/blob/master/index.d.ts
Our Users dataSource implementation:
import { MongoDataSource } from 'apollo-datasource-mongodb'
export class Users extends MongoDataSource {
}
The initiation in the context layer:
Users: new Users(legacy.collection('users'))
The call in the model layer:
async findOneById(obj, { id }, {dataSources: { Users }}) {
return await Users.findOneById(id)
}
We do not utilize mongoose & typescript in our project.
If anyone has any ideas on how to resolve this issue and make it work, please share!
