EAS Update: Error - Must specify codeSigningMetadata under the "updates" field of your app config file to use EAS code signing

I have a script to run EAS update. When I run this via GitHub Actions, sometimes it works and sometimes it returns the error in the title.

Any ideas?

A fix was recently released for eas-cli to make sure this error isn’t inadvertently triggered anymore. Make sure that you are on the latest version of eas-cli, and this should not happen anymore.
If you still run into this on the latest cli version, then feel free to open an issue in the eas-cli repo (Issues · expo/eas-cli · GitHub).
