I need to return PromiEvent (https://www.npmjs.com/package/web3-core-promievent) from async function. But I always got a common Promise without on handlers. Here is the test code: const Web3PromiEvent = require('web3-core-promievent')

async function sleep() {
    return new Promise((resolve) => setTimeout(resolve, 1000))
}

async function inner() {
    const pe = new Web3PromiEvent()

    await sleep()

    pe.eventEmitter.emit('done', 'ok')
    pe.resolve('ok')

    return pe
}

async function main() {
    const pe = inner()

    pe.on('done', console.log)

    const res = await pe
    console.log(res)
}

main()

Here the example in sandbox: https://codesandbox.io/s/node-js-forked-lw19bp?file=/src/index.js

How properly return PromiEvent from async function?
