Mailgun config setup

I have the same issue while I was updating the production.json file

I cross-checked the same provided JSON with https://jsonlint.com
it is indicating that there Is a problem with -

"mail": {
  "transport": "SMTP",
  "options": {
    "service": "Mailgun",
    "host": "smtp.mailgun.org",
    "port": 465,
    "secure": true,
    "auth": {
      "user": "postmaster@example.mailgun.org",
      "pass": "1234567890"
    }
  }
},
