Ingest Errors with Flexible Content Field Groups and WPGraphQL for ACF 2.0.0+

[alex-mmp]

Description

I'm encountering an issue with the ingest step of my Gatsby project after upgrading WPGraphQL for ACF to version 2.0.0+. Specifically, when using flexible content field groups in my WordPress ACF setup, the ingest process fails. Without the flexible content field group the build works absolutely fine.

This seems to have been a regression between version 0.6.1 and 2.0.0.

Steps to reproduce

1. Create a new WordPress installation.
2. Install and activate WPGraphQL and WPGraphQL for ACF.
3. Create a new ACF field group with a flexible content field.
4. Create a new Gatsby project and install the necessary WPGraphQL packages.
5. Configure the Gatsby project to connect to the WordPress site.
6. Run npm run develop in the Gatsby project.

PHP or JSON export of the ACF Field Group(s)
