Could not extract records from VCF file

[esraaelmligy]

I get the following error upon execution of the program on my vcf file generated on mm10 genome:

Reading and loading the VCF file, starting time is: 2023-07-10 13:34:23.802924909 UTC
thread 'main' panicked at 'called Result::unwrap() on an Err value: " reading the file failed: \n Could not extract any records from the provided file!! \n, formatting the string failed"', src/main.rs:13:83
note: run with RUST_BACKTRACE=1 environment variable to display a backtrace

This is the code i am running with:

./bins/Linux/vcf2prot -f ~/Freebayes.vcf -r ~/mm10.fa -v -g st -o results

Can you please specify the reason for this and how can i solve it? Thank you so much in advance.
