I’m having the same problem. Occurred after updating to latest expo-cli (3.19.2)
I’ve tried running expo build:ios with the --skip-credentials-check and --no-publish flags, no joy. I also tried installing the latest node.
I actually ran into this problem several months ago, but with expo upload:ios rather than expo build:ios. My solution then was to build normally, download .ipa from Expo, and then deploy using Transporter.
Is there another way to build these Expo apps? Through Xcode, perhaps?
Okay, I found a way to build for iOS. In the terminal, expo-cli will ask you something like “Do you have access to the Apple Developer account? Y/n”. Just say no. It will still build, so I could download the .ipa and deploy using Transporter.
