Error message when running "Convert" and "Make file" tool under Genome Diversity

I am getting the following error message when converting vcf file from 1000 genomes to gd_snp format: "a bytes-like object is required, not ‘str’ ".
I am getting the same error either using “Convert” or “Make file” tool under Genome Diversity option.
Please hepl! getting the gd_snp is crucial for me to move forward in my analyses.
