My question concerns the Camunda PHP SDK. My BPMN workflow contains a loop (“Sequential Multi Instance”) that I want to use for iterating over my custom collection class.
Up to now this class has methods like add() or toArray(), but there occurs an incident as I execute the workflow which is caused by my collection, so my current approach doesn’t work so far. Which methods are required by Camunda for iterating over it?
Many thanks.
