@simonbuerger We have spoken to the development team and they have some reservations about bundling the code from wp-graphql into the Peach Payments code plugin. We could consider building an extension in future that is managed separately. But this will be dependent on requests we get from users.
@simonbuerger we are taking a look at this. We will do a release in a future update with the support. I have logged this with the development team.
@dominicdacosta this would have been a compatibility issue with older versions of PHP. Do let me know if this is still happening. We released some update to fix the compatibility issues.
