Hi, I initially posted this in #CE6SDBX2A but on the advice of others wanted to share here. https://nfcore.slack.com/archives/CE6SDBX2A/p1784583827281509 If you run

nf-core pipelines launch nf-core/rnaseq -r 3.26.0

(or specify a different pipeline) without parameters, you get an uncaught traceback. Flagging for a fix

I think that is fixed in nf-core/tools 4.1.0. Can you try it with that? thanks for reporting!
