"Build succeeded" but still getting "There was an error..."

Bug description

Hello lovely community,

I'm trying out GameCI on GitHub Actions with the ubuntu-latest runner on Unity version 2021.3.16f1 for building WebGL. My first step which it already fails on is building the Addressable content.

Everything seems fine, since I'm gettings logs like:

2023-08-28T16:29:20.2936686Z Addressable content successfully built (duration : 0:07:34.394)
2023-08-28T16:29:21.0915668Z Addressables: finished with override version: 16
2023-08-28T16:29:21.0924390Z Batchmode quit successfully invoked - shutting down!
2023-08-28T16:29:32.7973754Z Exiting batchmode successfully now!
2023-08-28T16:29:32.9231549Z Build succeeded

But then I'm still getting this:

2023-08-28T16:29:37.8266881Z ##[error]There was an error building the project. Please read the logs for details.

The only errors I see are:

2023-08-28T16:13:00.0946253Z ##[warning]Fetch --unshallow caught: Error: Failed to run "git fetch --unshallow".
 In-command error caught: Error: The process '/usr/bin/git' failed with exit code 1

and:

My buildMethod is:

        public static void BuildAssetBundles()
        {
            Debug.Log("Addressables: Cleaning player content");
            AddressableAssetSettings.CleanPlayerContent();
            AddressableAssetSettingsDefaultObject.Settings.OverridePlayerVersion = GetVersion();
            Debug.Log("Addressables: Building player content"); 
            AddressableAssetSettings.BuildPlayerContent();
            Debug.Log("Addressables: finished with override version: " + AddressableAssetSettingsDefaultObject.Settings.OverridePlayerVersion);
        }
