Tutorial example Sector-Coupled does not run through for more countries: ValueError: zero-size array to reduction operation minimum which has no identity

[fhg-isi]

Checklist

• [x ] I am using the current master branch or the latest release. Please indicate.
• [ x] I am running on an up-to-date pypsa-eur environment. Update via conda env update -f envs/environment.yaml.

Describe the Bug

I started from the sector tutorial and changed the number of countries:

countries: ['AL', 'AT', 'BA', 'BE']

When running

snakemake -call all --configfile config/test/config.overnight.yaml

I get the error below.

=> Do the selected countries need to be neighboring countries/build a continuous area? If so, please include that information in the documentation and maybe also include a check and corresponding error message in the code.

Edit

With a different set of countries the workflow succeeds: ['BE', 'DE', 'LU', 'NL']
