Neutrino LTC: target height not found in index

[losh11]

Background

After enabling neutrino for LTC in lnd/config.go#651, using litecoin with neutrino fails to work.

Your environment

• LND: 0.5.2-99-beta (master)
• macOS 10.14.3

Steps to reproduce

On lnd/config.go#651: add case "neutrino":

then

$ lnd --neutrino.connect=127.0.0.1 --litecoin.mainnet --litecoin.active --litecoin.node=neutrino --debuglevel=debug

Expected behaviour

Neutrino should start syncing with LTC neutrino capable nodes.

Neutrino is not supported on mainnet at this time

[losh11]

Okay, same thing occurs with testnet. Please reopen.

[cfromknecht]

@losh11 this is known/expected behavior. There’s a reason the unmodified code gives the error “only ltcd and litecoind mode supported for litecoin at this time”

[kcw-grunt]

@cfromknecht is this an old issue. Is this still the case?

[ellemouton]

@kcw-grunt - Litcoin is no longer supported in LND
