Debugging with Node

Running the following command in VScode terminal does not properly bind to the default IP address of 127.0.0.1. The server errors with "WebSockets request was expected."

$(which hexo) clean && node --inspect-brk=4001 $(which hexo) server -i localhost -p 4001 --debug

Without Node Inspector

I observe if I run Hexo without node inspect, then Hexo will properly bind to both 127.0.0.1 and localhost.

$(which hexo) clean && $(which hexo) server --debug

Expected behavior

Server should accept both "localhost" and "127.0.0.1" on MacOS. Even with Node Inspector, it should respond correctly to IP and "localhost" as the domain.
