rename issue in nextflow

Hello,

I encountered an issue with nextflow on a HPC system (Roihu) and I am not sure how to solve it.

The error (from the .nextflow.log) file while running the test script is

Demultiplexing with LIMA (dual symmetric barcodes)

..Renaming demultiplexed files
Perl evaluation error: Can't modify constant item in predecrement (--) at (eval 1) line 1, at EOF
Bareword "filename" not allowed while "strict subs" in use at (eval 1) line 1.

The issue seems to point to this line:
echo -e "\n..Renaming demultiplexed files"
rename --filename
's/^lima.//g; s/--.$/.fq.gz/'
$(find LIMA -name ".fq.gz")

fi

I changed the rename from the linux utils (which does not work) and to the perl rename....

(base) [berninge@rc5144 ~]$ which rename
~/miniconda/bin/rename

Start with the test script and its .nextflow.log output, then inspect the rename command shown for the demultiplexed files and compare it with the Perl rename available at ~/miniconda/bin/rename. Done means the test script completes the LIMA demultiplexing step and renames the generated .fq.gz files without the Perl evaluation errors.
