Unable to function with `gridsome-source-graphql` as a source

When I try to use the gridsome-source-graphql source, the recommender plugin cannot find the specified option.typeName

The error message I receive is:

Gridsome v0.7.20

Initializing plugins...
gridsome-plugin-recommender: options.typeName 'craft' cannot be found - make sure the collection exists

I am using CraftCMS as a GraphQL data source. When I try to switch to the source-filesystem such as your example, then it does work, so I believe it's related to the async nature of retrieving the graphql data source and it not being loaded while the recommender loads in.

Here is an excerpt from my gridsome.config.js file which does not work.

  plugins: [
    {
      use: '@gridsome/source-graphql',
      options: {
        url: process.env.CRAFT_API_URL,
        fieldName: 'craft',
        typeName: 'craft',
        headers: {
          Authorization: `Bearer ${process.env.CRAFT_API_TOKEN}`,
        }
      }
    },
    {
      use: "gridsome-plugin-recommender",
      options: {
        enabled: true,
        typeName: 'craft',
        field: 'mainContent',
        relatedFieldName: 'related',
        minScore: 0.01,
        maxScore: 1,
        minRelations:3,
        maxRelations: 10,
        fillWithRandom:false,
        debug: false
      }
    },

Hi @thinkflo , this is indeed a problem.

The GraphQL plugin bypasses the collection layer where the gridsome-plugin-recommender hooks in and works direktly on the GraphQL layer.

In order to make that work you´d need to implement the whole logic on top of Graphql instead of collections, not sure if that is practical, although there seems to be a way to modify GraphQL nodes in a transformer

https://gridsome.org/docs/transformer-api/#example

Unfortunally I have no idea how to work with transformers, the documentation insufficient for my Gridsome knowledge level
