I am using a server that allows job submission via qsub. In the interactive mode, cutadapt works fine, but when I try to run a pipeline that uses cutadapt with qsub like : qsub -cwd run_script.sh I get the following error and trimming does not happen:

 Traceback (most recent call last):

FileNotFoundError: [Errno 2] No such file or directory: '${trimmed_dir}/r1.fq'

I have specified export PATH="/mnt/storage/apps/Python-3.6.13/bin:$PATH" at the beginning of my code, but still I get the same error.
