very much interested to use BPMN in our nodejs project. but when i try the sample,

Lets say,

start->task1->task2->end.

but not moving to task2.

kindly find the attachment of our sample and how to move or call or execute the task 2.

we are very much happy if this problem solves.

You’re probably in the wrong forum. This place is about bpmn.io and our modeling toolkits.
