This failure occurs when trying to package SunTemple for TVOS.
It did not occur with a blank blueprint project, until I added a custom iOS icon and tried to package a second time (I hypothesize there is a larger issue here: namely that on iOS we require a remote compile for blueprint projects when they have custom icons (by design); I'm making the assumption for now that this is affecting tvOS workflow here, and we didn't know it until now).
Error in the log:
Pop-up error to user:
SunTemple did not fail to package for IOS, only TVOS.
On tvOS this issue did not occur using a Code project with a custom icon (this is compatible with my hypothesis about the issue).
This was originally reported in [Link Removed] but with the different cross-section of platforms/samples, we've split them into two tickets to be tested separately.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-72832 in the post.
