Error running vds.summarize

Help [0.1]

Hey folks. I’ve got Hail running in Jupyter on a Dataproc cluster and it’s mostly working! Mostly.

I’ve managed to call import_vcf from a GCS bucket, write a vds, and call variantqc and export_variants on it.

Unfortunately when I call vds.summarize() I get a pretty gross looking error:

<decorator-gen-523> in summarize(self)

/hail/pyhail-hail-is-master-53e9d33.zip/hail/java.pyc in handle_py4j(func, *args, **kwargs)
    110         raise FatalError('%s\n\nJava stack trace:\n%s\n'
    111                          'Hail version: %s\n'
--> 112                          'Error summary: %s' % (deepest, full, Env.hc().version, deepest))
    113     except py4j.protocol.Py4JError as e:
    114         if e.args[0].startswith('An error occurred while calling'):

FatalError: NullPointerException: null

Hail version: 0.1-53e9d33
Error summary: NullPointerException: null

Any clues on what I’m doing wrong here?
