Hi, I tried to run Nirvana (last version 3.17.0) on the matrixtable and I got HailException: nirvana command failed with non-zero exit status 1 (hail log is attached) . There is no interesting error message and It just seems that the spark has a problem running the nirvana dotnet command.

I run hail locally in docker image (dockerfile attached), where the Nirvana was installed subsequently.  
When I used hail generated Nirvana command (from log) on my vcf it works well. Did I miss something?

Thank you Radim

I found using Nirvana workaround [here](https://discuss.hail.is/t/parsing-out-complex-json-or-dict-for-variant-annotations-from-nirvana/1947) .  
Thank you @thondeboer for your solution.
