Issue with Custom app submission in Freshteam: Node.js runtime version error

I encountered an issue while attempting to submit my app as a Custom app in Freshteam.
When uploading the app’s zip file, an error message is displayed stating, “Oops! We only support app manifests with Node.js runtime versions 14, 18 and above.

Here is the content of my manifest.json file:

  "platform-version": "2.2",
  "product": {
    "freshteam": {
      "location": {
        "job_boards": {
          "url": "ticket-sidebar.html",
          "icon": "styles/images/favicon.png"
  "whitelisted-domains": [""],
  "engines": {
    "node": "14.21.3",
    "fdk": "8.6.7"

I have validated the app package using “fdk validate,” and it returned a “Validation Successful” response. The node version mentioned in the manifest file is also 14.21.3.

If anyone in the community knows how to resolve this issue, your assistance would be greatly appreciated.

Thank you.

Hi Akanksha,

Please execute fdk pack command to convert file to zip file. use same zip file to upload to developer portal.

Please try and let me know if any issues.
