grant_type: 'authorization_code',

errno: 'EAI_AGAIN',

Answer 1

Based on Error: getaddrinfo EAI_AGAIN
"EAI_AGAIN is a DNS lookup timed out error, means it is a network connectivity error or proxy related error."
You may want to check if you have a proxy/firewall or other issues on the box making the API calls. This is a networking issue you need to fix that has nothing to do with DocuSign directly.

Answer 2

Thank you for the suggestion. But it was because I was not sending proper authentication.
I did use curl though for this :
curl
.setHeaders([
`Authorization: Basic ${auth}`,
"Content-Type: application/x-www-form-urlencoded"
])
.setBody({
grant_type: "authorization_code",
code: code
})
.post("https://account-d.docusign.com/oauth/token")
.then(({ statusCode, body, headers }) => {})
.catch(e => {});
