java.lang.ArrayIndexOutOfBoundsException when writing to vcf

[sandra-selfdecode]

I imported vcfs from several projects and combined them into one delta table. I am now trying to write from the delta table to a vcf, and I keep getting java.lang.ArrayIndexOutOfBoundsException when it tries to write to vcf.

Can you give me suggestions for what might cause this problem? It seems to be related to the genotypes column. It works if I only select genotypes.calls.

Hey Sandra, not sure what the issue is! Please print the schema for the dataframe, and provide some more info about the dataset (num variants and samples), and show the code and full stacktrace please?
