Hello Jitendra Kumar Kansal,
Thank you for awesome tutorial for beginners like me to walkthrough MDK process. I followed all the steps which you have mentioned.
I am following https://developers.sap.com/mission.mobile-dev-kit-get-started.html tutorial.
However, when i create destination in BTP cockpit and test then it throws me an error: Connection to "SampleServiceV2" established. Response returned: "404: Not Found"
Appearently, in the BAS while deplying it showing the error not able to deploy and no details found.
Any help would be useful.
