Assertion Error when union HT with unify is True

Hail Query & hailctl

Hi,

I would like to report an assertion error I had.
When I ran union command with unify=True (because my HT fields had different order), I got an assertion error, details as below:

# Union tables:
other_table = [gmkf2, tof]
union_table = gmkf1.union(*other_table, unify=True)

union_table.show()

And the error trace as below:
