Electrs returns fee -1 [Docker getumbrel/electrs]

[darkness-su]

Running BTC to XMR atomic swaps using configuration from:
https://github.com/UnstoppableSwap/asb-docker-compose

When calling estimate_fee, Electrs (Docker image getumbrel/electrs) returns -1 despite not showing any errors and bitcoind being 100% synchronized

Only warning that appears:
mainnet_electrs | [2024-11-13T05:29:09.030Z INFO electrs::electrum] your wallet uses less efficient method of querying electrs, consider contacting the developer of your wallet. Reason: blockchain.scripthash.get_history called for unsubscribed scripthash

-1 is sent back to the rpc client when estimate_fee returns Ok(None), estimate_fee forwards calls to bitcoind.
Does bitcoin-cli estimatesmartfee <blocks> return anything meaningful?

Currently it returns:

➜  mainnet git:(main) ✗ docker exec -it mainnet_bitcoind sh -c "bitcoin-cli -datadir=/bitcoind-data/ estimatesmartfee 3"
{
  "feerate": 0.00021084,
  "blocks": 3
}

Edited above with correct output
