Marketing Emails API is not responding properly with V3

Hi Team,

As part of the version change mentioned in below URL for Marketing Emails ( from v1 to v3 ), I’m getting no response post change addition.

URL : Solved: HubSpot Community – Marketing Email API: v3 released to general availability and upcoming sunset for v1 – HubSpot Community

I am able to get response with below API Call (v1) :  https://api.hubapi.com/marketing-emails/v1/emails?&limit=300&updated__range=1756857600000,1756944000000

Getting below response with API Call (v3) : https://api.hubapi.com/marketing-emails/v3/emails?&limit=300&updated__range=1756857600000,1756944000000
Response : URL response failed….Failing the TASK


Kindly suggest if any changes can resolve this issue and also let us know full API details as per v3 changes to be integrated.
