ERROR: LoadError: MethodError: PlotlyBase.savefig(::PlotlyJS.SyncPlot), ::String) is ambiguous #99

Hi,

This is the first time I'm trying to use VIVA. I followed GATK best practices to generate a vcf file that I want to visualise. I am using a cluster.

I ran: Julia viva -f 20190219_Gli1_5d_A03_Recalibratedhaplo_called.vcf -o viva_output/ -s pdf

And I got this error:
ERROR: LoadError: MethodError: PlotlyBase.savefig(::PlotlyJS.SyncPlot, ::String) is ambiguous. Candidates:
savefig(p::PlotlyJS.SyncPlot, a...) in PlotlyJS at /home/cluster/colpe/.julia/packages/PlotlyJS/AhkM5/src/savefig_orca.jl:1

Possible fix, define
savefig(::PlotlyJS.SyncPlot, ::AbstractString, ::Vararg{Any,N} where N)
Stacktrace:

Not sure what to do now...
I would greatly appreciate some help.
Kind regards
