[BUG] Cannot invoke method containsKey() on null object

[AlinaKurjan]

Describe the bug
Cannot run VSN-pipelines with any files due to the same error occurring regardless of the pipeline being run OR the file input format.

To Reproduce
Steps to reproduce the behavior:

1. Configure with these options:

nextflow config vib-singlecell-nf/vsn-pipelines \ -profile tenx,singularity,hg38,single_sample > single_sample.config

automatically generated config file always has a Warning message at the end saying the following: "WARN: Unknown config attribute params.global.outdir -- check config file: /home/a/akurjan/.nextflow/assets/vib-singlecell-nf/vsn-pipelines/nextflow.config"

2. Run using this entry point:

NXF_VER=21.04.3 nextflow -C single_sample.config run vib-singlecell-nf/vsn-pipelines -entry single_sample

3. See error:

N E X T F L O W  ~  version 21.04.3
Launching `vib-singlecell-nf/vsn-pipelines` [boring_bardeen] - revision: 6a9c70769b [master]

@AlinaKurjan were you able to solve this? I'm having the same issue.

Unfortunately not, had to do steps manually in the end.
