Vizier query_constraints returns "Empty TableList"

[hippke]

I try to pull a table from Vizier with some constraints, but get an "Empty TableList" result:
from astroquery.vizier import Vizier
result = Vizier(columns=["*"], catalog="IV/34/epic").query_constraints(ID="247887989")
print(result)

This is a bug. As a workaround, do:

result = Vizier(columns=["*"]).query_constraints(ID="247887989", catalog="IV/34/epic")

but I'll have a fix out shortly.

Thanks! Workaround works for me.
