We use

default: null

in a samplesheet schema (for numerical and string properties) but I just noticed this update to nf-schema to handle nested structures breaks this and now we get

[]

as the default for these properties instead: https://github.com/nextflow-io/nf-schema/commit/95f94407191539ce74c1088cf4c43cb64220e71b#diff-31134ce31200f1d463d2d0a8cf06313b93d4e4150eb4a3c97f57cb4bd3292164L141-R141

This will be fixed in the next version, we are aware of it 😅

Great! Sorry if I missed any issues on github, I did look!

No worries, it's in the 2.5.0dev branch right now if you want to test it. Just download the repo and run

make install

. Then set the nf-schema version to 2.5.0 and it should start working again

Thanks
