Description

After upgrading WordPress to version 6.7 and enabling WP_DEBUG, the following error/warning can be observed in the admin pages (at the very top, right under toolbar). This error/warning also shows up in the frontend.

Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the wp-graphql domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later. Please see Debugging in WordPress for more information. (This message was added in version 6.7.0.) in wp-includes/functions.php on line 6114

Steps to reproduce

• install WordPress version 6.7 or higher
• install WPGraphQL plugin, latest version (1.29.2 at the time of writing)
• set WP_DEBUG to true in wp-config.php
• observe the error/warning as described earlier
