Lnd: Unable to start node via docker

[duybach]

Background

I am following the guide from the README inside the docker folder. When I deploy "alice" and setup the BTCD node (by mining 400 blocks to activate segwit) I get this error when I check the logs from alice:

[ERR] NTFN: unable to get block: -32602: parameter #2 'verbosity' must be type int (got bool)

Your environment

The docker README tutorial was working for me a few days ago. Today I had to redo the docker containers and after removing the containers & volumes, I've encountered this problem. Tried it also on my other device (Ubuntu & Windows).

Steps to reproduce

$ export NETWORK="simnet" 

$ docker-compose run -d --name alice lnd_btc
$ docker exec -i -t alice bash

alice$ lncli --network=simnet newaddress np2wkh 

$ MINING_ADDRESS=<alice_address> docker-compose up -d btcd

$ docker-compose run btcctl generate 400

$ docker logs alice
[ERR] NTFN: unable to get block: -32602: parameter #2 'verbosity' must be type int (got bool) 

Expected behaviour

My LND node should be able to get the blocks.

Actual behaviour

LND Node can't read block because:
[ERR] NTFN: unable to get block: -32602: parameter #2 'verbosity' must be type int (got bool)

This error is coming from btcd. It looks like a PR was recently merged that changed the behavior there and lnd isn't compatible with the newest version yet. Can you try changing your docker/btcd/Dockerfile from

RUN git clone https://github.com/btcsuite/btcd.git . \
    &&  GO111MODULE=on go install -v . ./cmd/...

to

RUN git clone https://github.com/btcsuite/btcd.git . \
    &&  git checkout v0.20.1-beta && GO111MODULE=on go install -v . ./cmd/...

and then building the image again?

Thanks for the solution. Node is working now :+1:
