vg construct throwing error "what(): Found unexpected delimiter in fastq/fasta input"

[champ1994]

1. What were you trying to do? I was trying to construct graph using construct module from /test/1mb1kgp fasta and vcf

2. What did you want to happen? I ran the command

./vg construct -r z.fa -v z.vcf.gz -S -p > z.vg 

3. What actually happened? It threw following error

terminate called after throwing an instance of 'std::runtime_error'
  what():  Found unexpected delimiter  in fastq/fasta input
ERROR: Signal 6 occurred. VG has crashed.
