How to enable “Potentially unhandled rejection…” in gulp instead of Error:?

Question

gulp.js

I don't know what I did for this, but one of my projects displays gulp errors as "Potentially unhandled rejection..." and gulp never crashes, so I don't have to restart it. But errors in other projects look like Error: and blah blah blah and always crashes.
Please explain to me what should I do to make all my projects show errors as "Potentially unhandled rejection..." and no
crashes All this when using gulp watch

Answer 1

The reason was a new version of gulp less. There are errors like "Potentially unhandled rejection ..." + and does not crash.
