How to upload to gulp server with watch?

Question

gulp.js

Hello!
Help with gulpfile.js. By default (gulp command) builds sass and starts the watcher. It is necessary that after the assembly there was an unloading on the server.
Now the gulp deploy command runs, but when the tracked file changes, it gives an error:

[17:35:04] Starting 'deploy'...
Changes detected! Uploading file "undefined", undefined
[17:35:07] 'deploy' errored after 3.88 s
[17:35:07] Error: Invalid glob argument:
