gatsby-transformer-react-docgen - Error: Schema must contain unique named types but contains multiple types named "JSON".

Description

Installed the gatsby-transformer-react-docgen plugin, but get this error message:

$ gatsby develop

error UNHANDLED REJECTION


  Error: Schema must contain unique named types but contains multiple types named "JSON".

  - Array.forEach

  - Array.forEach

  - Array.forEach

  - Array.forEach

  - Array.forEach

  - Array.forEach

If I remove the filesystem path to my components this error goes away, but the point is to read the components.

What could I be missing?

Still having this issue. Added a link to the repo to reproduce. @Chuloo

To fix this, we'd need to PR a fix to how the docgen transformer creates node type names. Anyone interested in doing this? I can give some pointers

[jonearley]

@KyleAMathews I could take a look. Where should I start?

https://github.com/gatsbyjs/gatsby/blob/445f5ff7508ab613967e18b32490e3feffd7730c/packages/gatsby-transformer-react-docgen/src/on-node-create.js#L106

@KyleAMathews Still have this issue since August. A few others have 👍'd it. Could this be investigated?

Still experiencing this issue with the latest package versions. I try every month or so to see if this works.
