gene2transcript error for gene LYST

[AnotherSimon]

I'm getting a server error message when trying to retrieve the transcripts for the gene "LYST"

http://my.local.server:8000/VariantValidator/tools/gene2transcripts/LYST?content-type=application%2Fjson
{
  "message": "Internal Server Error"
}

Curiously enough validation of specific transcript variants works just fine:
