Hey, I removed that updating field code immediately after and the problem persisted.
I found a random unrelated chunk of code that was causing the error. I don’t know why it is causing it though. I don’t know if it’s the unrelated code’s fault, or ACF’s fault, or some strange interaction between the two.
Any time I run wp_insert_post() or wp_update_post() on a page load that occurs within WP Admin, the issue I described shows up. When I deleted all calls to those, everything worked again. I am using them to sync a post type to an external API. Perhaps those two functions require an attachment to a special hook that I’m not using? Any thoughts on that?
