Hi all?
I have a quality-of-life question. When running Hail on DNAnexus, my notebook often gets disconnected while code is running (e.g. I need to close my laptop). I understand that I can use a JupyterLab magic command, e.g.
```
%%capture out
# a bunch of hail commands in a cell
```
and subsequently use `out.show()` to view the output. This works when the cell doesn't produce an error. When the cell produces an error, though, `out` is essentially empty. It would be very useful to capture the error so that I have an idea of how to troubleshoot. Any suggestions?
I've posted this question to the Hail forum as well.
Best,
Jeremy

Hi @Jeremy Chang?,
I would be interested in knowing if the Hail error messages would be captured by the Spark UI: https://documentation.dnanexus.com/developer/apps/developing-spark-apps#monitoring-the-spark-ui
