KeyError: '2': always met this error when converting a vcf file to phylip file.

[mxtu97]

I have modified the variety names to be four digits, such as 4111, ensuring they are within 10 characters. However, I am still encountering this error. Could you please teach me how to resolve it?

$ python3 vcf2phylip-2.8/vcf2phylip.py -i test.vcf
