lancet issue when vcf NOT filtered by PASS

When VCF is not Filtered by PASS, the genotype for variants contains dots and not zeros or one such as: GT:AD:SR:SA:DP .:0,0:0,0:0,0:0 1/1:0,5:0,0:4,1:5

Having a dot will raise an error while running script addFieldsForVcfMerger2:

Traceback (most recent call last):
