Description: my native iOS App integrated with Salesforce production, and user can upload pictures from App to Salesforce working well before. But today it's not working, all users got error message "An unexpected error occurred. Please include this ErrorId if you contact support: 1436668424-30151(-1219322115)". Also upload pictures in Salesforce1, got same error. By the way, it works fine in Sandbox.
