RPC error on invoice creation

[Filiprogrammer]

The following RPC error occurs when trying to create an invoice:

2023-12-31 00:13:54.242 [INF] LNADDR: Handling invoice creation: {GET /invoice/?amount=10000&nonce=179879833238 HTTP/1.1 1 1 map[Accept:[/] User-Agent:[curl/7.88.1]] {} 0 [] false 127.0.0.1:8081 map[] map[] map[] 127.0.0.1:43232 /invoice/?amount=10000&nonce=179879833238 0xc0002733c0}

This issue is present since commit 01b5d1a

Tested with lnd v0.16.0-beta

Problem solved. I had "RPCHost" set to "localhost:8080" in the config.json. So I was still trying to access the REST API on port 8080 even though the new version of go-host-lnaddr uses gRPC which runs on port 10009. The solution was to change the "RPCHost" to "localhost:10009".

I also noticed that the "RPCHost" value in the config.json example file is incorrectly set to "localhost:9735". This should be changed to "localhost:10009".

-        "RPCHost": "localhost:9735",
+        "RPCHost": "localhost:10009",
