Comment:

 @dd32 how can you make that the gallery items have no attached IDs?

 I'm unable to reproduce this just by calling to
 `get_post_galleries($post_id, false);` as you suggest.
 I'm not confident that the reproduction report of rolly is what you mean,
 afaik, thereis not `id` but `ids`

 I understand that you can trigger this when `ids` happens to be empty and
 the function is trying to pluck an empty string throwing such error. But I
 have not found a way to create a gallery that has an empty `ids` string.

 If I add a gallery without images, this is the result

 and no array at all

 If you are asking at this moment why I have put screenshots instead the
 text? Only god knows, I was thinking this right now, but it's too late now
 for me to rollback
