I am trying to create a panel of normal following this guide - https://gatk.broadinstitute.org/hc/en-us/articles/360035531132--How-to-Call-somatic-mutations-using-GATK4-Mutect2

I have split the genome into chromosomes and created genomic DB using them. However, when trying to combine the output from CreateSomaticPanelOfNormals, I'm getting a weird error. Any help is appreciated!

REQUIRED for all errors and issues:
a) GATK version used: v4.2.6.1

b) Exact command used:

time gatk GatherVcfs -I chr1:1-123463784.vcf.gz \
-I chr1:123463784-248956422.vcf.gz -I chr2:1-92988518.vcf.gz -I \
chr2:92988518-242193529.vcf.gz -I chr3.vcf.gz -I chr4.vcf.gz -I \
chr5.vcf.gz -I chr6.vcf.gz -I chr7.vcf.gz -I chr8.vcf.gz -I \
chr9.vcf.gz -I chr10.vcf.gz -I chr11.vcf.gz -I chr12.vcf.gz -I \
chr13.vcf.gz -I chr14.vcf.gz -I chr15.vcf.gz -I chr16.vcf.gz -I \
chr17.vcf.gz -I chr18.vcf.gz -I chr19.vcf.gz -I chr20.vcf.gz -I \
chr21.vcf.gz -I chr22.vcf.gz -I chrX.vcf.gz -I chrY.vcf.gz -I \
chrM.vcf.gz -O pon.vcf.gz
