EAS build - rsync error: some files could not be transferred (code 23) error

When creating an iOS EAS build, I get the following error during the Run Fastlane step:

› Executing MyApp » [CP] Embed Pods Frameworks

❌  rsync error: some files could not be transferred (code 23) at /AppleInternal/Library/BuildRoots/97f6331a-ba75-11ed-a4bc-863efbbaf80d/Library/Caches/com.apple.xbs/Sources/rsync/rsync/main.c(996) [sender=2.6.9]

So after some research, I got the following answers which are somewhat related (those were answered for flutter/ionic though),

I think it is due to new cocoapods and Xcode v14.3, but as i'm using EAS for building my iOS app and not on local machine, I cannot just update the cocoapods on my local machine, as all the build process is taking place in EAS server, so how can I solve this issue particularly when using eas build.

package.json:

"expo": "^46.0.0",
"react": "18.0.0",
"react-dom": "18.0.0",
"react-native": "0.69.6",

Podfile:

require File.join(File.dirname(`node --print "require.resolve('expo/package.json')"`), "scripts/autolinking")
require File.join(File.dirname(`node --print "require.resolve('react-native/package.json')"`), "scripts/react_native_pods")
require File.join(File.dirname(`node --print "require.resolve('@react-native-community/cli-platform-ios/package.json')"`), "native_modules")

platform :ios, '12.4'

          if (build_phase.respond_to?(:name) && build_phase.name.eql?('[CP-User] Generate Specs'))
            target.build_phases.move(build_phase, 0)
          end
        end
      end

    installer.target_installation_results.pod_target_installation_results
      .each do |pod_name, target_installation_result|

        end
      end
    end
  end
end

Any help would be really appreciated!

Solution

You can edit your eas.json profile to include the CocoaPods and Xcode image that you want to use to build your project.

"profileExample": {
  "ios": {
    "cocoapods": "1.12.1",
    "image": "macos-monterey-12.6-xcode-14.2"
  }
}
