[Seqan-dev] Mason2 exception error



Hello, I use mason2 to create paired-end reads as shown bellow:

./mason_simulator -ir /home/chris/Desktop/GRCh38_latest_genomic.fa --num-threads 12 -n 1000000 --illumina-read-length 150 --input-vcf /home/chris/mason_output/variation/hg_out.vcf --out /home/chris/mason_output/simulator_output/pair_end_left_reads.fq --out-right /home/chris/mason_output/simulator_output/pair_end_right_reads.fq


and I get the following error:

I really don't know where is the problem.
Any advice would be very helpful. 

Thank you,
