ERROR bwt » JSON error: invalid type: sequence, expected a string

[drew1kun]

Hi, I am asking for help to understand what am I doing wrong here.

I have been trying to set up my Electrum Wallet on OSX to connect to my Bitcoin Core Full Node via both Bwt server(docker) and BWT-electrum-plugin without success. Both bwt-electrum-plugin and BWT docker return the same message... They seem to be able to connect to bitcoin node via RPC but reporting the same error from BWT:

DEBUG bwt » Config { network: Bitcoin, verbose: 1, timestamp: false, bitcoind_wallet: Some("tangem_cold"), bitcoind_dir: Some(""), bitcoind_url: Some("http://bitcoin.domain.local:8332"), bitcoind_auth: Some("**SCRUBBED**"), bitcoind_cookie: None, create_wallet_if_missing: true, descriptors: [], xpubs: [xpub<XXXXXXX>], addresses: [], addresses_file: None, rescan_since: Timestamp(1735603200), force_rescan: false, gap_limit: 20, initial_import_size: 350, wait_sync: true, prune_until: None, auth_cookie: None, auth_token: None, auth_ephemeral: false, print_token: false, electrum_addr: Some(127.0.0.1:51315), electrum_skip_merkle: true, electrum_socks_auth: false, poll_interval: 5s, broadcast_cmd: None, startup_banner: false, unix_listener_path: Some("/Applications/Electrum.app/Contents/MacOS/electrum/plugins/bwt/bwt-socket"), require_addresses: true, setup_logger: true }

WARN bwt::progress » getblockchaininfo failed: Json(Error("invalid type: sequence, expected a string", line: 0, column: 0))
ERROR bwt » JSON error: invalid type: sequence, expected a string

It seems like my Bitcoin Core node returns the unexpected Json response over RPC... Which makes me think that my Bitcoin Core node might be misconfigured... But, when I connect the Sparrow Wallet directly to my Bitcoin full node (without using any intermediary electrum-like server etc..), all works as expected.

Anyway, my bitcoin.conf:

Please help me to understand what is wrong with my BWT/Bitcoin Core setup. Thank you.
