Camunda springboot - Can't find scripting engine for 'groovy': scriptEngine is null

Hi

I am facing the problem as below when starting the workflow. Workflow is deployed on embedded Camunda in a micro service. Just to give the background I used DMN as part of BPMN & implementing it as part of a Business Rule task with implementation as ‘DMN’. In DMN, decision table uses groovy expression.

Cannot instantiate process definition bpm-drug:1:505ff1f2-7153-11e9-a44d-ded63d2e4778: Can’t find scripting engine for ‘groovy’: scriptEngine is null

Can you please let me know what may be the problem.

Here is my pom.xml:
