| # This example demonstrates a workflow accepting a list of items (as JSON string) | ||
| # as an input parameter, and using it for expanding a step into a sequential task | ||
| # of arbitrary steps. When a step fails, the iteration will break, stopping | ||
| # following steps from running. | ||
