Deployment issues using Camunda modeler

Hi i created a small bpmn diagram. I tried deploying it through Modeler. My deployment failed and i got the below error message in my log file. Can you help me out?

The error message basically explains your problem in deatil

You have a service task that needs implementation.

Thank you Niall. The issue is solved
