snakepipes: error in chip-seq using Genrich as mapper

I stumbled upon this error:

Sample sheet found and header is ok!

---- This analysis has been done using snakePipes version 2.7.3 ----
Sample sheet found and header is ok!

InputFunctionException in line 164 of /home/tgeorgom/mambaforge/envs/snakePipes/lib/python3.11/site-packages/snakePipes/shared/rules/ChIP_peak_calling_spikein.snakefile:

 Spikein genome detected - at least one spikeIn chromosome found with extention _spikein .


Error: snakemake returned an error code of 1, so processing is incomplete!

the command is:

ChIP-seq -d /mnt/c/AP04/ -j 8 --local --useSpikeInForNorm --getSizeFactorsFrom genome --peakCaller Genrich  --sampleSheet /mnt/c/AP04/PolII.tsv --w
indowSize 500 --plotFormat "pdf"  mm10_gencodeM19_spikesTEST /mnt/c/AP04/PolII_ChIPtype.yalm

the samplelist is:

and the yalm file for the peak type is:
