What does this bcf error mean?

I ran this code to filter out biallelic variants from my vcf file: bcftools view --max-alleles 2 --exclude-types indels merged.ecDNA.vcf.gz>merged.ecDNA2.vcf.gz However, I got an error message: [E::vcf_parse_format] Number of columns at 1:219048632 does not match the number of samples (111 vs 231) Error: VCF parse error The thing is, merged.ecDNA2.vcf.gz still appeared in my directory and it seems to be a working vcf file. So I was wondering, if my code actually produced a vcf file that appears to be normally functioning, would the above error still have any effect on my output file? What should the number 1:219048632 refer to? I tried this code too: bcftools view -m2 -M2 -v snps merged.ecDNA.vcf.gz>merged.ecDNA3.vcf.gz And I got the same error message for the above code. If anyone could give a general explanation of what that error message means, it would be super helpful.
