I'm not sure if the mentioned PR is addressing all the issues mentioned in the issue. I'm also facing the issue with the wrong chain param for the regtest network. The prefix_bech32 value must be bcrt @mccwdev

After some more testing and digging i found out that

When wallet.scan() is called in our case, BitcoindClient.gettransactions(wallet_address, '', 20) is called and fails

error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/data/.local/lib/python3.8/site-packages/bitcoinlib/services/bitcoind.py", line 223, in gettransactions
    raise ClientError("Address %s not found in bitcoind wallet, use 'importpubkey' or 'importaddress' to add "
bitcoinlib.services.baseclient.ClientError: Address bcrt1qn... not found in bitcoind wallet, use 'importpubkey' or 'importaddress' to add address to wallet.

When changing res['iswatchonly'] = True
wallet.scan() works and the balance is updated.

My workaround for now is pointing to a custom data directory as follows:

[locations]
# Location of BitcoinLib data, configuration and log files. Relative paths will be based in installation directory
data_dir=./data

In the BCL_CONFIG_FILE and then fixing the networks.json file for my own use case.

P.S. You need to replicate all the required files in the data directory: https://github.com/1200wd/bitcoinlib/tree/master/bitcoinlib/data
