nightwatch could not find my step definition file - cucumber

Question

I am doing a POC for my project. When i do run a sample test with below project structure am facing a error as mentioned. Any help on this is much appreciated.
I have my project structure as below.
and my conf file content is like below.
require('nightwatch-cucumber')({
cucumberArgs: [
'--require', 'features/step_definitions',
'features',
]
});
module.exports = {
output_folder : 'reports',
custom_assertions_path : '',
page_objects_path : 'page_objects',
live_output : false,
disable_colors: false,
globals_path : '',
selenium : {
start_process : true,
server_path : './bin/selenium-server-standalone-3.9.1.jar',
log_path : '',
host: '127.0.0.1',
port : 4444
},
test_settings : {
default : {
launch_url : "https://<url>",
selenium_host : '127.0.0.1',
selenium_port : 4444,
desiredCapabilities : {
browserName : 'chrome',
javascriptEnabled : true,
acceptSslCerts : true
}
},
chrome : {
desiredCapabilities : {
browserName : 'chrome',
javascriptEnabled : true,
acceptSslCerts : true
},
selenium : {
cli_args : {
'webdriver.chrome.driver' : './bin/chromedriver/chromedriver'
}
}
}
}
};
and the saturnLogin step file has
const { client } = require('nightwatch-cucumber')
const { defineSupportCode } = require('cucumber')
// const { Given, When, Then } = require('cucumber')
defineSupportCode( ({Given, When, Then}) => {
Given(/^I login SATURN application with "(.*?)" and "(.*?)"$/, (user, pass) => {
console.log("Manimaran....")
const loginPage = client.page.saturn_login()
return loginPage
.navigate()
.setValue('#userName', user)
.setValue('#passWord', pass)
})
})
and the package.json file has
{
"name": "nightwatch-poc",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"mytest": "nightwatch -e chrome"
},

"license": "ISC",
"dependencies": {
"cucumber": "^4.1.0",
"nightwatch": "^0.9.20",
"nightwatch-cucumber": "^9.1.2"
}
}
When i run my test, i am getting the error as below.
λ npm run mytest
