Hi everyone! Here is my error which I get with Nextflow v25.10.0 build 10289:

Execution cancelled -- Finishing pending tasks before exit
-[ComputationalRegulatoryGenomicsICL/customcage] Pipeline completed with errors-
WARN: Got an interrupted exception while taking agent result | java.lang.InterruptedException

Line 6 in

cageflow/modules/nf-core/samtools/faidx/main.nf

is, actually, the container definition for the newly-added nf-core faidx module:

container "${ workflow.containerEngine == 'singularity' && !task.ext.singularity_pull_docker_container ?
        '<https://depot.galaxyproject.org/singularity/samtools:1.22.1--h96c455f_0>' :
        'biocontainers/samtools:1.22.1--h96c455f_0' }"

It does have the standard Nextflow

task

variable but it is very strange that this variable is not recognised in this context in our pipeline. The error looks suspiciously similar to the ones arising from Nextflow's quirk of variable evaluation that Ben Sherman posted about here -- https://github.com/nextflow-io/nextflow/issues/4215 -- but in the container definition, the

task

variable is within a big dynamic string, which means that it should be evaluated per task run, and so, everything should be fine. We would be very grateful for any advice!
