Hi, Has anyone managed to catch the exceptions thrown by Appian and

Integration nodes are generally what cause exceptions (that aren't obvious during design time) and are required to be handled. The method to handle such excpetions differ based on the node that is used. For example, DB nodes come with a provision to pause or exception or continue with error. Web service nodes could be wrapped in a sub-process with a timer/retry logic in the parent model. An automated process to review the process with problem report is another option to handle exceptions.

Here are some links that provide good documentation on error handling/exceptions:
