SmartSettings NullReferenceException

I'm getting the following error where it appears the SmartSettings object is null in LiteralText.toString(). Using version 0.9.

Code looks like:

Code (CSharp):

1.  
2.     public LocalizedString TimeString;
3.     public string TimeNow => "5 Hours";
4.  
5.     private void OnEnable()
6.     {
7.         TimeString.Arguments = new[] { this };
8.         TimeString.StringChanged += OnTimeStringChange;
9.     }
10.  
11.     private void OnDisable()
12.     {
13.         TimeString.StringChanged -= OnTimeStringChange;
14.     }

Errors on the TimeString.StringChanged += OnTimeStringChange part.

Looks like its probably the same issue as this https://forum.unity.com/threads/nre-with-list-formatting.985803/. Happens only if I toggle the smart checkbox. Once checked, even if the string is empty, even hitting the preview button in the LocalizedStringEvent UI triggers the error in the editor. I've had to work around this by keeping the smart checkbox disabled and manually using Smart.Format myself which isn't ideal. I'm using Unity 2020.2.1 but also noticed it on 2019.18 LTS. Mac OS.

 

Here's a screenshot of my String Database settings.

 

Yeah just filed one. Do you know what that setting should be?

 

So I was able to fix the issue by just deleting and recreating the LocalizationSettings asset.

 

I had the same issue, it may have been caused when I updated Localization from version 0.8.x to 0.9.0.
And like speppers, I had the INVALID_UTF8_STRING operator and it was fixed by recreating the LocalizationSettings asset from scratch.
