@notbrent thanks that worked for the archive , however I came to my initial problem that is the following error.
ERROR ITMS-90022: "Missing required icon file. The bundle does not contain an app icon for iPhone / iPod Touch of exactly ‘120x120’ pixels. I started having this issue 2 days ago with sdk 40 , tried adding new icons , however this error persists. Any idea of where I can debug this issue. I assume it has to do with the Expo eject step not generating the correct icons for some reason. Currently already upgraded to sdk42
Thanks
