I’m getting nodejs runtime 18 error while uploading zip file of manifest

Here is my manifest code

  "platform-version": "3.0",
  "product": {
    "freshdesk": {
      "location": {
        "ticket_sidebar": {
          "url": "https://c00d-106-216-239-239.ngrok-free.app"
        }
      }
    }
  },
  "name": "Contact Form App",
  "version": "1.0",
  "author": "Your Name",
  "defaultLocale": "en"
}

Hi @Kanishka,

Your manifest.json has invalid attributes.
Can you please check the documentation and fix them by only adding what are valid properties?

Hey,

Could you help me navigate to proper articles using which i can associate my fronend / backend application to ticket side bar or anywhere.
