Directory not found universc

[HafsaKM]

Hi! Quite new to this, I am trying to run the scrna-seq pipline and I keep running into this error. I just wanted to run this piepline with the universc alignment tool on a small test.

This is the shell script I used

#!/bin/bash
#PBS -l walltime=24:00:00
#PBS -l select=1:ncpus=16:mem=64gb

module load tools/prod
module load Nextflow/23.10.0

nextflow run nf-core/scrnaseq \
  --input /rds/general/user/hk1723/home/test_files/sample_sheet.csv \
  --outdir /rds/general/user/hk1723/home/test_files/results \
  --genome GRCh38 \
  --aligner universc \
  -profile singularity \

This was in the execution report file

Workflow execution completed unsuccessfully!
The exit status of the task that caused the workflow execution to fail was: 1.

The full error message was:

Tip: view the complete command output by changing to the process work dir and entering the command `cat .command.out`

The directory it says it couldn't find, I thought that would be created by an internal program, not sure why it hasn't been created? Thanks so much for your answers!
