React Native (Expo) build fails with error 65 at archive step

[Pravez]

If you are looking for help, please confirm the following...

• I confirm I have searched the Docs, Codemagic Sample Projects, and GitHub Discussions.
• I confirm the software versions on my local computer match the ones in CI environment (e.g. Xcode version, Gradle version). See here
• I confirm I am able to do a fresh clone of the repository and build the project on my local computer.

Which mobile framework are you using?

React Native

Steps to reproduce

Base React Native project with Expo configuration and some plugins, nothing fancy, no specific app capabilities (or I missed something).

Expected results

The archive step to work.

Actual results

Everything seems to look great, until the archive step where it fails with no more information. Tried to see eventual logs through XCode via VNC, nothing much appeared. Only warnings, nothing that was seen (or that I could find) in recent discussions.
Tried to use XCode 16.2 instead of 16.3, nothing changed.

Maybe it is a signing problem ? I am aiming to distribute my app through Firebase App Distribution, so my certificates are for distribution and ad-hoc.

I noticed the following during the automated "Set up code signing identities" :

Add certificate /Users/builder/Library/MobileDevice/Certificates/code_signing_certificate_jh6x4tni.p12 to keychain /Users/builder/Library/codemagic-cli-tools/keychains/01-06-25_cl7ttbbd.keychain-db
security: SecKeychainItemImport: Unable to decode the provided data.
1 key imported.
1 certificate imported.

This unable to decode the provided data is suspicious.

hello @Pravez please try adding the archive flag to your build command

xcode-project build-ipa \
  --workspace "$CM_BUILD_DIR/ios/$XCODE_WORKSPACE" \
  --scheme "$XCODE_SCHEME" \
  --archive-flags="-destination 'generic/platform=iOS'"    

[Pravez]

It worked, thank you ! To be honest, I saw this flag in another post, just didn't think it was necessary in my case.
