When using VariantSpark interface for Hail to run important analysis, VariantSpark expect to have exactly one allele in REF and ALT field. If there was any issue (some dataset have . in the ALT field) the process fails but it does not report which variant causing the error. So it is difficult for user to Understand and fix the problem.
I suggest to report the offending line when loading data fails to complete.
