GraphQL query error since gatsby-transformer-remark 2.7.4 release

[mabhub]

Description

Build fail when gatsby-transformer-remark is upgraded (from either 2.6.59 or 2.7.3) to 2.7.4

(Issue may be related to 82c05aa)

Steps to reproduce

As the issue seems to rely on async processing and depending on amount of GraphQL nodes to process, I wasn't able to create a minimal reproduction test case. But the project I'm working on is open source, so you may reproduce the error with it:
Build may take several minute to complete

$ git clone --branch test-case --depth=1 https://github.com/solagro/awa.git
$ cd awa
$ npm ci && npm run build
$ # Build success

$ npm i gatsby-transformer-remark@2.7.4
$ npm run clean && npm run build
$ # Build fail

Expected result

Successfull build

Actual result

Build error

[...]

success Building production JavaScript and CSS bundles - 55.534s

I can definitely reproduce, but it seems unreasonably difficult to debug what exactly is happening - for some reason attaching debugger makes the problem not reproducible anymore

Adding at least stack trace of where the error happens:

More to follow

[pieh]

Ah, seems like this was already discovered ( #21188 (comment) ) and fixed ( #23427 ) in master, but not yet published to npm. I will publish this tomorrow (finishing for today)

[pieh]

So for today, please pin to previous gatsby-transformer-remark, and next publish should fix this as well.

I applied same fix from #23427 locally and couldn't reproduce the problem anymore.
