Connector Error | One of the attributes 'class', 'delegateExpression', 'type', or 'expression' is mandatory on serviceTask

Hi All,

I created a sping boot project from and wanted to implement connectors in the same.

I got the following error one running the project
2020-06-24 14:11:08.351 ERROR 16132 — [nio-8080-exec-3] org.camunda.bpm.engine.context : ENGINE-16004 Exception while closing command context: ENGINE-09005 Could not parse BPMN process. Errors:

  • One of the attributes ‘class’, ‘delegateExpression’, ‘type’, or ‘expression’ is mandatory on serviceTask. | resource restcallProcess.bpmn |

I understand that since this isn’t the pre-packaged version, i could be lacking some dependencies or plugins. Could anyone point out where i can add the right dependencies to resolve this issue ?
I have configured a rest connector, and am pretty sure that is configured correctly.

Thanks in Advance,

Can you upload the model you’re created?
