Proxy option leads to uncaught exception if passed without protocol

See original GitHub issue

Reproduce by running:

http-server --proxy google.com

You will get an error link this:

/Users/moritzkneilmann/.config/yarn/global/node_modules/requires-port/index.js:13
  protocol = protocol.split(':')[0];
                      ^

TypeError: Cannot read property 'split' of null
    at required (/Users/moritzkneilmann/.config/yarn/global/node_modules/requires-port/index.js:13:23)

    at Object.exports.(anonymous function) (/Users/moritzkneilmann/.config/yarn/global/node_modules/ecstatic/lib/ecstatic/status-handlers.js:37:5)

This is no issue if --proxy https://google.com is used.

PS: thanks for this package; it’s an essential tool for testing for me 👍

What is the solution for this? I tried everything. For me it’s working fine in windows PC. But not in mac. It was working fine earlier. Now it gives the error TypeError: Cannot read property ‘split’ of null. required-port
