Current behavior

When ng add @ng-toolkit/serverless I got an error

Error: socket hang up at createHangUpError (_http_client.js:323:15) at TLSSocket.socketOnEnd (_http_client.js:426:23) at TLSSocket.emit (events.js:187:15) at TLSSocket.EventEmitter.emit (domain.js:441:20) at endReadableNT (_stream_readable.js:1094:12) at process._tickCallback (internal/process/next_tick.js:63:19) Emitted ‘error’ event at: at TLSSocket.socketOnEnd (_http_client.js:426:9) at TLSSocket.emit (events.js:187:15) [… lines matching original stack trace …] at process._tickCallback (internal/process/next_tick.js:63:19) npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.2.4 (node_modules/fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.2.4: wanted {“os”:“darwin”,“arch”:“any”} (current: {“os”:“linux”,“arch”:“x64”})
