riak-ts: can't delete keys

[jamesruan]

I'm using a ts 1.5.2.

select * from logv2 where time > '2018-03-15 00:00' and time < '2018-04-15 00:00' and type = 'log'

[1522235100839, "go logger client", "log", "[DEBUG]", "test log debug"], 
[1522235100880, "go logger client", "log", "[TRACE]", "test log trace"], 
[1522235100919, "go logger client", "log", "[INFO ]", "test log info"], 
...

delete from logv2 where time > '2018-03-15 00:00' and time < '2018-04-15 00:00' and type = 'log'

500 Internal Server Error trying to execute query
