playwright: [BUG] Filechooser seems to fail for me

Hi, I was trying upload few files using playwright, but it seems to fail for me. I assume I might be doing something wrong.

Details: Playwright Version: 1.6.2 Operating System: Windows 7 Node.js version: 12.18.0 Browser: Firefox

Code:

const {
  firefox
} = require('playwright');
const path = require('path');

// Add youtube email & password
let email = 'xxxxxxx@email.com'
let pass = 'xxxxxxxxxxxx'
let filePath = path.join(__dirname, 'xxxxxxxxxxx.mp4')

async function begin(){
   const browser = await firefox.launch({
        headless: false
      })
     const context = await browser.newContext()
 
    const page = await context.newPage()
    await page.goto('https://www.youtube.com/upload')

    await page.fill('input[type="email"]', email);
    await page.click('text=Next');
    await page.fill('input[type="password"]', pass);
    await page.click('text=Next');
    await page.waitForLoadState();
 await page.on('filechooser', async (fileChooser) => {
     console.log("filechooser called")
      await fileChooser.setFiles(filePath)
  })

  // Button that initiates filechooser event
  await page.click('text=Select files');

}

begin()

Log:
