Bug report - my colleague's pipeline was failing with

ERROR ~ No such variable: revpr_R1

on version 4.3.1, but working on 4.1.0 and 4.2.x. I traced it to a missing variable definition in

subworkflows/local/presto_umi.nf

around line 359. Replacing the reference

revpr_R1

here with

params.primer_revpr

(default: false) results in the pipeline working, when run directly from the edited pipeline source locally. The change (removing

def revpr_R1 = false

and not removing

revpr_R1

later) was apparently introduced in a 2024-09-27 commit.

Thank you for the report @Kelvin Hunter, I’ve made a bug report on GitHub and will fix this before the next release https://github.com/nf-core/airrflow/issues/410
