Haplogrep error with a vcf-merge file.

[VGDEC]

Hi,
I have created a merged vcf file using vcf-merge tool for ~1000 samples.
When I am trying to provide this file as an input for the haplogrep, it is showing the following error:

Kindly, please suggest what should be done.

Thanks, can you provide a minimal input file? Looks like there is a variant included in the file with an AF of ".". (We currently allow an AF of > 0.0).
