I run the following commands:
horizon db clear horizon db backfill
2018/03/24 14:29:55 network-passphrase is blank: reingestion requires manually setting passphrase
How to reingest the history?
Your command looks fine, but you need to set some more variables. It says your "network-passphrase" is blank.
It wants this variable either via the envvar (Environment Variable)
NETWORK_PASSPHRASE, or as a flag
--network-passphrase="XXX" when running your horizon command.
For certain horizon commands, you may also need the 3 flags from here.
