GetBuildPropertyForConfig doesn't return anything

I'm trying to set up a post-process build script to first check for an existing entitlements file before creating a new one. But even when I know there is one, it returns null.

Code (CSharp):

1. project.AddBuildProperty(targetGUID, "CODE_SIGN_ENTITLEMENTS", relativeDestination);
2. string existingEntitlements = project.GetBuildPropertyForConfig(targetGUID, "CODE_SIGN_ENTITLEMENTS");
3. Debug.LogFormat("=> {0}", existingEntitlements);

 

GetBuildPropertyForConfig takes a config GUID as a parameter, but you're passing in a target GUID. You could use GetBuildPropertyForAnyConfig, otherwise you'll have to get the build config GUID first with BuildConfigByName.
