if a graph is not found while executing a call node throw an exception if there is no catch block. A catch block here means an outcome with the value "catch" attached to the call node.

In diagram one if the called graph cannot be found no exception is thrown because there is a connected catch block. The record node will execute, the graph will continue executing and execute the execute block.

In diagram two if the called graph cannot be found a SvcLogicException will be thrown. Execution will not continue, the execute block will not be executed.
