"Rich text" field makes a ERROR #11321 PLUGIN

Hi,

I can't figure out what I am missing for sourcing Rich text fields from Strapi. Also I am sorry if this isn't a plugin bug, I'll post in on StackOverflow otherwise.

I just started a new Gatsby blog with the official starter. Then I followed the instructions to source Gatsby with Strapi.

Creating a basic Collection Type with a simple text field
Creating a new Entry for that Collection Type
Giving access find and findOne to PUBLIC users
Generating a public API Token
Updating gatsby-config as the following (for testing purpose I made it the bad way without .dotenv) :

const strapiConfig = {
  apiURL: `http://localhost:1337`,
  accessToken: `my-token`,
  collectionTypes: [`my-collection-type`],
  singleTypes: [`simple-single-type`],
};

and

{
  resolve: `gatsby-source-strapi`,
  options: strapiConfig,
},

See gatsby-config.js.txt

Everything looks fine as I can see the my collection nodes in Graphql.

Now, I add a Rich Text field in 'my-collection-type' :

This makes Gatsby crash

"gatsby-node.js" threw an error while running the createPages lifecycle:

However, I can see my Collection type in GraphiQL :

{
  "data": {
    "allStrapiMyCollectionType": {
      "edges": [
        {
          "node": {
            "id": "74341941-4e66-5bd4-a646-afecf997571f",
            "richtext": {
              "data": {
                "id": "f0edc79a-69da-5758-869f-2da62c17a044",
                "internal": {
                  "content": "Hello"
                }
              }
            }
          }
        }
      ]
    }
  },
  "extensions": {}
}

I saw some explanations about Rich text fields on the plugin documentation, but I am unsure of what to do with it.

Also here is my config :

Gatsby CLI version: 4.16.0
Gatsby version: 4.19.1
Node v16.15.1
Strapi 3.1.0-alpha.5

Would anyone have an hint for me ?

Thank you, Grégoire
