Error when running the script "The "path" argument must be of type string or an instance of Buffer or URL"

Hey, I saw below error when trying to run the script:

~/add-tradingview-alerts-tool ❯❯❯ npm run add-alerts

> @alleyway/add-tradingview-alerts-tool@1.5.2 add-alerts
> npx tsc && node -r source-map-support/register lib/add-tradingview-alerts.js

Using config file:  config.yml
Press Ctrl-C to stop this script
TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string or an instance of Buffer or URL. Received undefined
    at Object.open (node:fs:473:10)

    at constructNT (node:internal/streams/destroy:288:25)
    at processTicksAndRejections (node:internal/process/task_queues:80:21)

I was able to login to tradingview and the chart was loaded. Before it was able to add any alert, I got this error.

My config is as following:

files:
  input: software.csv
tradingview:
  # The chart which has the indicator you'd like to use
  chartUrl: https://www.tradingview.com/chart/xxxxx/ 
  # (optional) set the chart interval before adding pairs, otherwise interval of last saved chart is used
  # examples: 1s | 30s | 1m | 15m | 1h | 1D | 1M
  interval: 30min
alert:
  option: Once Per Bar Close
  actions:
    notifyOnApp: false
    showPopup: false
    sendEmail: false
    webhook:
      enabled: true
      url: "https://xxxxx"
  # alert name is optional - can override in csv if you add a "name" column. can use {{symbol|base|quote}}
  # name: "MI dev3 for {{base}} {{quote}}"
  # indentation matters! {{quote}} and {{base}} are swapped out for quote asset(eg. USDT) and the base (eg. BTC)
  # message: >
  #   {
  #        "message_type": "bot",
  #        "bot_id": 999999,
  #        "email_token": "fffffff-fffff-fffff-ffff-ffffffffff",
  #        "delay_seconds": 0,
  #        "pair": "{{quote}}_{{base}}"
  #   }

Is it because I commented out some optional fields? Thanks!!
