bpmn-server / BusinessRuleTask

Class: BusinessRuleTask#

Evaluates the decision camunda:decisionRef names, in the models folder: the file <ref>.dmn.xml, or a decision with that id. Its inputs are read from the instance data and the task's input parameters (which take precedence); the result is the task's output, saved in the data by output parameters or camunda:resultVariable, shaped by camunda:mapDecisionResult (singleEntry, singleResult, collectEntries or resultList) when that is set.

failed#

▸ failed(item, error): Promise\<NODE_ACTION>

The task's work threw.

Otherwise the item's status is error, with the message, saved so the instance shows it and the item can be retried (engine.retry), and the exception is thrown to the caller as before.
