I am trying to add dependency in Manifest.json file.

//manifest.json

{
  "platform-version": "2.2",
  "product": {
  "freshdesk": {
	"events": {
        "onTicketCreate": {
        "handler": "onTicketCreateHandler"
        }
      }
  }
  },
  "dependencies": {
	    "nodemailer": "6.6.5"
  },
  "whitelisted-domains":[]
}


At fdk run, getting the following error:

FDK version: 6.13.1
Node.js version: v12.22.9

Earlier the dependency adding was working. Based on my debugging the error is related to the dependency section only. Is it related to FDK version upgrade to FDK 7 ?

Hi Rupendra Sharma
Good day!

Welcome to Freshworks Developer Community!

I tried adding the same nodemailer dependency to my app in local and it installed successfully.
FDK version - 7.3.0.
Node version - v12.22.9 and v12.18.2

Can you try upgrading to fdk 7 and try again - FDK v7.0 - Announcing Node.js v12 and ES6+ support.

Another solution that seems to have worked for many - https://github.com/nodejs/help/issues/2874

@banu thanks, although I have assumed the same while adding this question here and already upgraded the FDK to 7.0. it is resolving the dependencies now so all good.

Now I think @Freshworks should focus on updating the platform documentation and the FDk template apps so that new app should be automatically targeting the v2.2. Or I have missed some announcements?
