gatsby 4 - cannot call `createTypes` in the `sourceNodes` API

[cameronbraid]

Are there plans to support gatsby 4 on the way ?

Technically the toolkit just provides you the tools and you use them in gatsby APIs you need. In other words, the toolkit user should take care of calling createSchemaCustomization and sourceNodes in corresponding gatsby APIs.

We should probably update the docs and maybe make it a bit more convenient in the toolkit. But it should be compatible as-is.
