custom Request
Send a custom request to the lavalink node. Any host and port you set will be replaced with the node host automatically. The scheme must match your node's scheme, however.
It is recommended to use the path setter instead of the url setter when defining a url, like this:
{@code customRequest((builder) -> { return builder.path("/some/plugin/path") .get(); }).subscribe(System.out::println); }
Return
The Http response from the node, may error with an IllegalStateException when the node is not available.
Parameters
builder Fn
The request builder function, defaults such as the Authorization header have already been applied
