Only legacy wallets are supported by this command

[dbligh]

Hi, I'm trying to follow the installation guide but hitting some issues on testnet executing npm run bitcoin using the ION generated wallet import string.

npm WARN lifecycle The node binary used for scripts is /snap/bin/node but npm is using /snap/node/7026/bin/node itself. Use the `--scripts-prepend-node-path` option to include the path for the node binary npm was executed with.

In trying to get this working I've started bitcoind to support legacy wallets using:

./bitcoind -conf=/home/administrator/bitcoin-27.0/bitcoin.conf -testnet -deprecatedrpc=create_bdb -daemon

And created a legacy wallet:

$ bitcoin-cli -testnet -conf=/home/administrator/bitcoin-27.0/bitcoin.conf -named createwallet wallet_name=ion_wallet_legacy passphrase=<passphrase> descriptors=false

Produces the following output:

{
  "name": "ion_wallet_legacy",
  "warnings": [
    "Wallet created successfully. The legacy wallet type is being deprecated and support for creating and opening legacy wallets will be removed in the future."
  ]
}

I'm now stuck trying to get the right value from here to put into bitcoinWalletOrImportString.

Any idea where I'm going wrong here?
