[bug]: Unable to run lnd 0.18.3rc2 with bitcoin core v28.0rc1

[bufo24]

Background

I am getting an error after unlocking lnd:

Sep 01 16:32:46 bitcoin-mainnet lnd[423674]: 2024-09-01 16:32:46.792 [ERR] LTND: unable to create partial chain control: unable to determine if bitcoind is pruned: unable to detect bitcoind version: json: cannot unmarshal array into Go struct field GetNetworkInfoResult.warnings of type string
Sep 01 16:32:46 bitcoin-mainnet lnd[423674]: 2024-09-01 16:32:46.792 [ERR] LTND: Shutting down because error in main method: error creating wallet config: unable to create partial chain control: unable to determine if bitcoind is pruned: unable to detect bitcoind version: json: cannot unmarshal array into Go struct field GetNetworkInfoResult.warnings of type string

Your environment

• lnd v0.18.3-beta.rc2
• Linux 6.1.0-21-amd64 Debian 6.1.90-1 (2024-05-03) x86_64
• Bitcoin v28.0rc1

Steps to reproduce

I upgraded bitcoin core from v27.0 to v28.0rc1, while lnd was still on v0.18.0, got the error as describe above. Then I upgraded lnd to v0.18.3rc2 and still got the same error.

Expected behaviour

LND should run with bitcoin core v28.0

Actual behaviour

LND cannot start using bitcoin core v28.0 as backend

Thanks a lot for testing with the RC! This was broken by bitcoin/bitcoin#29845. I've created a fix here: btcsuite/btcd#2245.

Please also open an issue on the Bitcoin Core when something like this happens... :-)

I would be useful to know if the current Lnd master branch works now that barebitcoin/btcd#4 was merged (I don't see a new Lnd tag).
