Caught exception invoking method 'PreExport': parameters do not match signature

Our UCB has been building successfully for some time now but all of a sudden, today we started getting an error on the Pre export method.

The pre exported method is defined as follows

public static void PreExport (UnityEngine.CloudBuild.BuildManifestObject manifest)

Is there anything that I’m missing? The weird thing is that this only happened on iOS, everything was fine on Android.

Thank you,

The signature of your pre-export method looks correct. More likely some function you are calling inside your pre-export method is being called with the wrong set of parameters. Any exceptions caught running your pre-export method will show up after the ‘Caught exception invoking’ part, so it’s potentially confusing as to whether the issue was invoking the pre-export method itself or some code inside of it.
