Snakemake version : 7.32.4,
python version : 3.10.14,
linux ubuntu system

I am experiecing a problem with snakemake that no matter what I do , it does not get resolved. It also changes the KeyError when I do a small change to the output file name in my rule.
for example if I change from from this:
forwardPaired=”results/cutAdapt/{sample}-{unit}.1.fastq.gz”,
reversePaired=”results/cutAdapt/{sample}-{unit}.2.fastq.gz”,
to this:
forwardPaired=”results/cutAdapt/{sample}-{unit}_1.fastq.gz”,
reversePaired=”results/cutAdapt/{sample}-{unit}_2.fastq.gz”,

I get a different KeyError:
Error:
KeyError: (‘ShS-DIF4-rep1’, ‘FC2.1’)
Wildcards:
sample=ShS-DIF4-rep1
unit=Take1

take into consideration that ‘ShS-DIF4-rep1’ should match ‘FC1’ unit in my units dataframe

Thank you in advance for the help.

I am expecting for respective ‘ShS-DIF4-rep1’ to match ‘FC1’ and same from other sample to match their respective unit column for the same row from my units.tsv table.
