NodeExecutionException

A node's action threw an exception. The original exception is available as cause.

Every exception is wrapped, also a TelarException: when a node runs another graph or calls a model of an integration module, cause is the exception of that graph or model. So is what a browser throws in place of an exception, such as the Error of a request that got no response. An error of the program or of its machine is not wrapped: a subclass of Error, such as OutOfMemoryError, AssertionError or the NotImplementedError of TODO().

Cancellation of the run itself is never wrapped: it propagates as a CancellationException. A CancellationException that a node raises while the run is still active, such as an expired withTimeout inside the node, is a failure of that node and is wrapped like any other.
