> If there is invalid definition/json in alert definition then Upgrade would 
> fail with below exception. there is no way to determine which alert is 
> causing the issue here.
> its not clear how this alert definition gets corrupted but we have seen this 
> with 3 to 4 customers already - printing the alert definition name would he 
> helpful in support point of view to determine the root cause.. other wise it 
> is very difficult to find it out - had a give a dev patch to customers to 
> find it out.
