When alpha is connected to zero,invalid memory address or nil pointer dereference

Hey, can you post the version of dgraph and the commands you ran?

dgraph version:

zero commands:
dgraph zero --idx 101 --my=IP:7180 --port_offset=2100 --wal …/data/zw --replicas 3

alpha commands:
dgraph alpha --idx 200 --lru_mb 2048 --my ##.##.##.159:9080 --zero ##.##.##.159:7180 --postings …/data/p --wal …/data/w

I think the correct command for running dgraph alpha would be:

dgraph alpha --idx 200 --lru_mb 2048 --my ##.##.##.159:7080 --zero ##.##.##.159:7180 --postings …/data/p --wal …/data/w
