lnprototestの備忘録

以下のlnprototestにてテストを走らせたところエラーが起きたのでその備忘録

https://github.com/rustyrussell/lnprototest

実行環境

• ubuntu 20.04
• lnprototest: master
• core-lightning: master
• bitcoin core:  v25.0

テスト実行すると以下のエラーとなる。rpc周りのエラーっぽかったので、bitcoin.confなどの設定をしてみたが解決には至らず。

結局、ビットコインコアのバージョンをv22へ下げてみたらテストが通った。この検証にまる3日ほどかかってしまった泣。実行結果は以下参照。
