I'm running dash-qt v0.14 on Mac OS Catalina in regtest mode with the following configuration file:

server=1
daemon=1
rpcuser=test
rpcpassword=test
rpcport=18445
regtest=1

I'm sending the following payload to the RPC:

{"jsonrpc": "1.0", "id": "225397719705", "method": "generatetoaddress", "params": [101, "yddiN2CfWvwPPcnkMrZA7U2sC8EJstDkwU"]}

The address yddiN2CfWvwPPcnkMrZA7U2sC8EJstDkwU is part of my wallet, as it's been generated using the getnewaddress method.

I'm getting the following response:

{"result": null, "error": {"code": -32601, "message": "Method not found"}, "id": "225397719705"}

All other endpoints work perfectly fine, except generate.

Also, I have very similar configuration for bitcoind and litecoind clients, and generatetoaddress method works perfectly fine in both cases, it's only in Dash where it's not working.

Any idea why?
