Schema fails to load when field group is cloned on many different flexible content layouts

[jasonbahl]

Description

When an ACF Field Group is cloned onto many different ACF Field Groups, the schema fails to load.

Steps to reproduce

1. With the following plugins active:

• WPGraphQL v1.23.0
• ACF PRO v6.2.7
• WPGraphQL for ACF v2.2.0
• WPGraphQL IDE 1.1.0 (optional)

2. Import the following ACF Field Groups export: dev-site-acf-backup2.json

3. Try to load the GraphiQL IDE

Expectation:
IDE loads and I can browse the schema and test queries, etc

Actual:
IDE fails to load the schema and outputs the following errors:

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

dev-site-acf-backup2.json (also referenced above)

Additional context

This appears to maybe be caused by the array_merge_recursive() within WPObjectType and WPInterfaceType that implements fields from Interfaces onto implementing Interfaces and Object types.

Additionally, there appears to be some recursive functions that could bail early within WPGraphQL for ACF.

The issue seems closely related to:

• Group field types
• Clone field types
• Interface fields being applied to other Interfaces / Object Types
