Xcode Cloud - Command PhaseScriptExecution failed with a nonzero exit code

I've been running into issues with Xcode Cloud/my workflow when it's trying to archive the app. I've tested locally and both archiving and building the app for release works. I've tried a few things to clear it.

1. pod deintegrate and pod install
2. Checking off "archive" for the build scheme
3. Creating a certificate for both development and distribution. I made sure automatic signing was enabled as well.
4. I have a ci_scripts/ci_post_clone.sh script that successfully completes.
5. Have tried setting the xcode version of the workflow to 16.2 which is what my local xcode version is. I've switched it back to the latest, 16.4.
6. running pod update
7. Updating flutter

However, I consistently get the following 2 errors :

Any help here would be greatly appreciated.
