Sass and express give error which is not shown with concurrently. My command concurrently --kill-others "npm run build:js" "sass -w scss:public/assets/" "npm run start:server" runs and compiles but after a moment it exits and saying -

[0] npm run build:js exited with code 0
--> Sending SIGTERM to other processes..
[1] sass -w scss:public/assets/ exited with code 1
--> Sending SIGTERM to other processes..
[2] npm run start:server exited with code 1

But running them alone seperately does not give any errors My javascript command "build:js" uses rollup.

It was running just find before, but the moment I close my editor and reopened it after sometime it start giving problems. Any ideas?
