Bug ArgumentOutOfRangeException with Initial setup

This is my code :

Code (CSharp):

1.  
2. public class AnalyticsManager : MonoBehaviour
3. {
4.     async void Start()
5.     {
6.         try
7.         {
8.             await UnityServices.InitializeAsync();
9.             List<string> consentIdentifiers = await AnalyticsService.Instance.CheckForRequiredConsents();
10.         }
11.         catch (ConsentCheckException e)
12.         {
13.             // Something went wrong when checking the GeoIP, check the e.Reason and handle appropriately.
14.             Debug.LogError($"User did not consent {e}", this);
15.         }
16.     }
17. }
18.  

And when launching the app, this is what I get in the Cloud Diagnostic Crash & Exception

Code (CSharp):

1. ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
2. AnalyticsManager+<Start>d__1.MoveNext () (at <00000000000000000000000000000000>:0)

What I don't get is that I dont read the consentIdentifiers List, so I don't understand why it gives me an "Index is out of range" error.
