VT tools can`t input reference when attempting to normalize a VCF file

Question

[genome21]

When running a normalization function from the Vt tools (http://genome.sph.umich.edu/wiki/Vt) I have:

normalize v0.5

options:     input VCF file                                  DecomposedPilonReducedresult.vcf
         [o] output VCF file                                 VTPilonVCF.vcf
         [w] sorting window size                             10000
         [m] no fail on masked reference inconsistency       false
         [n] no fail on reference inconsistency              false
         [q] quiet                                           false
         [d] debug                                           false
         [r] reference FASTA file                            H37Rv_reference.fasta

executor.ExternalCommandFailed: External command failed with exit code 1! (command: bash -c 'bash ./norm.sh')

Does anybody know how to eliminate this errors and what are the reasons?

The link in the error message is surprisingly informative (hint, you're probably using the wrong fasta file).
