`gatsby build` fails because `node.internal.content` is undefined

Problem

gatsby build fails because node.internal.content is undefined in getOrgAST in orga-util.js:line 49 compiled in node_modules/ when evaluating GraphQL's term html.

In TypeScript, here https://github.com/orgapp/orgajs/blob/2fc346ed2481faff2355a894acda72aa1fc0352e/packages/gatsby-transformer-orga/src/orga-util.ts#L48

The error Cannot read property 'indexOf' of undefined occurs in read in text-kit because the 'string' passed from node.internal.content is in fact undefined.

I'm making a project using gatsby-transformer-orga referring to https://github.com/orgapp/gatsby-orga . Then I encountered this error when I added many org files to src/pages/.

How can I do fix this error?

Reproduction

• This error does not occur when there are a few org-files in src/pages/.
• This error occurs by adding many org-files to src/pages/. (Although I don't know contents are matter or not, the error did not occur by adding just many files that are same content.)
• But I could not reproduce the org-file which causes this error. After npm run clean, the file varies. (I don't know why.)
• When the error occurs, orga-util.js:line 49 is called only one time. (At the time, node.internal.content is undefined)

I prepared a sample project. Please do npm install, then npm run build causes this error.
