Problem & Solution Description (including issue #)

Code Quality

• My code follows the code style of this project
• I have written unit tests or justified all instances of #pragma: no cover; in the case of a bugfix, a new test that breaks as a result of the bug has been added
• My code contains relevant comments and necessary documentation for future maintainers; the change is reflected in applicable demos/tutorials (with output cleared!) and added/updated docstrings use the NumPy docstring format
• Any breaking changes, described above, are accompanied by backwards compatibility and deprecation warnings

Originally, if one of the iterators doesn't have any input data the output will complain. I used sys.exit to free the unused nodes, but I'm guessing this messes with the next stages in a pipeline. Still, I think it needs somehow to tell the unused nodes not to expect an output

[eacharles]

Can we catch the issue in the writing of the output?

Looks good

Let's wait and hear more from Josue about how we might solve downstream issues before we merge this one.
