Loopback-next: 'npm start' on lb4 app fails with error "events_1.once is not a function"

[SumanBandopadhyay]

Facing issue while starting with the loopback 4 "getting-started" application.
All steps were followed as mentioned in the link to set up a new lb4 application.

After the application got created, the 'npm start' was unable to start the application.
[Note: I did not make any change to the project after it was created.]

Below is the error after trying to start the application.
`npm start

[email protected] restart ....\hello-world
npm run build

[email protected] build ....\hello-world
lb-tsc

[email protected] start ....\hello-world
node -r source-map-support/register .

Cannot start the application. TypeError: events_1.once is not a function

What’s your node version? We require 10 or above.

The once method was added in: v11.13.0, v10.16.0. See https://nodejs.org/api/events.html#events_events_once_emitter_name. Please use Node.js 10.16.0 or later.
