how to add variant from vcf

[a00101]

Dear developer

docker run --rm -v variants_PASS.vcf:/variants_PASS.vcf -v sandy_db:/sandy/db galantelab/sandy variation add --verbose -a entry variants_PASS.vcf
:: Inserting entry from variants_PASS.vcf ...
:: Checking if there is already a structural variation 'entry' ...
:: structural variation 'entry' not found
:: Indexing 'variants_PASS.vcf'
:: It may take a while ...
sandy variation add: Argument "0/1" isn't numeric in numeric eq (==) at /usr/local/lib/perl5/vendor_perl/5.36.0/x86_64-linux-gnu/App/Sandy/DB/Handle/Variation.pm line 248, <$fh> line 49.

I used genome-generator based on specific vcf for making genome with variation from vcf and random mutation.
vcf is from strelka2 germline

Thank you in advance.
