I am dealing with some problems using the REST API for a process instantiation.
I have a very simple process (start → step1 ->end) without contracts. The process definition ID is 7710269580874956548.
Connecting using the walter.bates user and posting /API/bpm/process/ with payload
{
"processDefinitionId": "7710269580874956548"
}
I get the following 500 error:
