Checklist

I have read the contribution guidelines.
Unit tests have been added for any new or changed code, and the test suite passes. Note: Your request will likely not be merged without the appropriate tests.
"closes #XXXX" is in the body of the MR description to link the related issue, if applicable.

In principle it would be wise to add tests for these things, but I think it's easier to actually make the code more reliable by restructuring it

guard against accidental "None" in espresso inputfiles. Fix the stdout location
