Mutect2 analysis results in a empty output bam file and a vcf file with only the header

Hello, I write to report a problem I encountered while using Mutect2.

In short, I performed pre-processing on two sets of paired-end fastq files (control and tumor) according to the gatk4 best practices. Then I perform Mutect2 analysis with this command:

gatk --java-options "-Xmx2g" Mutect2 -R /path/ucsc.hg19.fasta -I S3.bam -I S1.bam -tumor tumor -normal ctrl --germline-resource /path/af-only-gnomad.raw.sites.hg19.vcf --af-of-alleles-not-in-resource 0.001 -disable-read-filter MateOnSameContigOrNoMappedMateReadFilter -O 1_somatic_m2.vcf.gz -bamout 2_tumor_normal_m2.bam -L exons.bed

I do not get any errors, the last lines of the st output look like this:

20:53:49.380 INFO ProgressMeter - chrUn_gl000249:36601 361.1 13527466 37460.5

However the output bam file and is empty, and the output vcf file contains only the header; what I am doing wrong?

I also tried to run the command without the -L flag.

Thank you in advance.
