Hi,
As mentioned in this post, I'm getting a WARN log on UserFriendsCache class in following line :
var user = AsyncHelper.RunSync(() => _userManager.FindByIdAsync(userIdentifier.UserId.ToString()));
I think it is caused when a user is disconnected.
This is causing a lot of log lines :

I'm running on ASPNET CORE 3.1, Angular 9.1, Abp 5.5
Any fix possible for next deliveries ?

hi
As mentioned in the previous question, this does not cause any problems, it just appears in the log.
