Mutect on mm10

Hello,

I am trying to run mutect on mouse, and getting the following error ERROR MESSAGE: Unable to parse header with error: Your input file has a malformed header: VCFv4.2 is not a supported version, for input source: /cromwell_root/fc-f36b3dc8-85f7-4d7f-bc99-a4610229d66a/broadinstitute/reference/mm10/129S1_SvImJ.mgp.v5.snps.dbSNP142.with_chrom.sorted.vcf

The VCF is of version 4.2. Is this really not supported? Is there an easy fix? Thanks
