Description
HttpClient::SendRPCMessage() throws an ERROR_RPC_INTERNAL exception on all HTTP 2xx responses other than 200:
long http_code = 0;
curl_easy_getinfo(curl, CURLINFO_RESPONSE_CODE, &http_code);
if (http_code != 200) {
throw JsonRpcException(Errors::ERROR_RPC_INTERNAL_ERROR, result);
}
A user is experiencing a situation where an RPC server is returning a 201 response, see https://stackoverflow.com/questions/57492037/. The request is successful, but SendRPCMessage() fails.
The check of the http_code value should be more like this instead:
if ((http_code / 100) != 2)
