I tried the same
expo build:ios without the --config command and it does run. So it seems to be an issue with the build system - the app.json files are identical except for slugs and package’s.
It’s a silent failure all I get is:
“No logs exist” and when I click them I get this:
Your build is errored. 2 No logs exist for this build yet. Once a build has logs they will appear here.
