Are you using camunda spring boot deployment model?

Possible root causes are:

  • Class com.workflow.SearchFalloutTicket is not found in the camunda server classpath.

  • Might be configured wrongly in the bpmn model.

  • Due to Heterogeneous cluster setup and deploymentAware=true property.

Can you upload your bpmn file and the class com.workflow.SearchFalloutTicket ?
