Right now our support for malformed VCFs is pretty limited. This is a terrible error message, though – I’ve made an issue to track it (https://github.com/hail-is/hail/issues/2232).
I don’t think this is an rsID issue, since the type says “Int32” there, which leads me to believe this is an INFO field value which contains 2 values even though the header field says there should be just one. When we fix the error message, it should be much easier to see what’s going on.
As an aside, the fact I’m seeing “Int32” and not “Int” means you’re using the
devel version of Hail. I would strongly recommend that you use the
0.1 version, partly because we’re not going to answer
devel-specific questions, and there are bugs in the development version that aren’t in
