Description

Create a flow where a processor has scheduling strategy set to event-driven with concurrent tasks set to 0. Start version control on the flow, and them try to import a new process group using the flow from previous step.

The error is because during import we set the concurrent tasks value before the scheduling strategy, and StandardProcessorNode line 630 throws an exception if the tasks is < 1 and strategy is not event driven.

The exception also does not report any message so it is hard to figure out what the issue is.
