Getting "connect ECONNREFUSED" error when I "npm run seed" in feathers api with mongodb - mongodb

Question

I'm learning react and feathers. For my recipes app that I've made in react I use feathers api and mongodb. I have some seeds as examples in /src/seeds.js and just began to set up everything in feathers but when I want to run my seeds(npm run seed) and check if it works on feathers localhost:3030/recipes I got this error:
Error creating user! { Error: connect ECONNREFUSED 127.0.0.1:3030
at Object.exports._errnoException (util.js:1022:11)
at exports._exceptionWithHostPort (util.js:1045:20)
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1087:14)
code: 'ECONNREFUSED',
errno: 'ECONNREFUSED',
syscall: 'connect',
address: '127.0.0.1',
port: 3030,
response: undefined }
I don't know the error is because of connection or creating user!
I checked my mondo db, it runs.
this is package.json, just in case:

}
Before adding seeds I should have seen {"total":0,"limit":5,"skip":0,"data":[]} in http://localhost:3030/recipes that I'm still having it but after running seeds I should see the list of my recipes.
Anythings else that I need to copy here from my code? any idea?
