Hey @Elliot Condon! I currently have the same issue in all my environnments. The gallery field is inside a repeater and the ajax response is empty. It looks like the JS field_key attribute is undefined and thus, not sent to the backend.
In pro-input.js I can cleary seen that this.settings.key returns undefined if I use inline js debugging.
var data = acf.prepare_for_ajax({
action : 'acf/fields/gallery/get_attachment',
field_key : this.settings.key,
nonce : acf.get('nonce'),
post_id : acf.get('post_id'),
id : id
});
If I replace with this it works but it’s not a good solution (but maybe it can help you debug a little bit)
var data = acf.prepare_for_ajax({
action : 'acf/fields/gallery/get_attachment',
field_key : acf.get_data(this.$el.parents('tr'), 'key'),
nonce : acf.get('nonce'),
post_id : acf.get('post_id'),
id : id
});
Cheers!
Great plugin by the way!
Update: seems to happen only when I export to code (php) and I delete the group in the UI. It works well when I it stays in the UI.
