error.converter: unsupported operand type

[loipf]

hi all,

I am trying to annotate a project .vcf file retrieved from GLnexus with OpenCRAVAT.
the .bcf file file gets converted to an .vcf file with:
bcftools view <bcf_file> | bgzip -c > pvcf_all_glnexus.vcf.gz

oc is installed with conda install open-cravat==2.2.1.
if I run this file with oc run -l hg38 -t csv -x pvcf_all_glnexus.vcf.gz
for most of the lines it works perfectly but for some I get the following errors in the err log for multiple lines:

the subset of the input .vcf file looks like this (2. and 5. line are problematic, one line before and after the error is included for comparison) :

I cant really see any obvious difference between these lines. can you help me if this error is already in the .vcf file and OpenCRAVAT is supposed to skip these cases or just a bug ?
Thank you in advance !

Well look into this and get back to you. Thanks a lot for the detail here.
