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?

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