Oncotator error---IndexError: list index out of range

I used Oncotator (1.9.3.0) to annotate VCF file.
If I run this on command line:
oncotator -v --input_format VCF --output_format TCGAMAF --db-dir /share/apps/oncotator_v1_ds_April052016/ -d . test_oncotator_ffpe.vcf oncotator.maf hg19

There will be an error：
