Activiti nested subprocess issues

Hi.I'm working on something in work, and can't figure out where the issue resides - Activiti or in our RestTemplate calls. We're using 5.16.1We're using activiti as a dependency in a service, where it handles various patterns like sub process nesting, and other complicated patterns. Lately we've bee

I'll be able to attach stack traces and bpmn's tomorrow. Also, does each subprocess get it's own engine, or do they all share one?

I've attached the logs that I've seen in activiti:

This is the complete task failure message we get:
Caused by: "OurOwnServiceException" Can't complete task 130029: 404 Not Found.
This is persisted back from activiti.

Basically, why does a direct manual curl command to Activiti return the proper error message, and our subprocess call to activiti does not?

Can anybody help me with this? I've spent a few days trying to debug this, but the issue remains the same. Activiti is not returning the exception from the subprocess, so further up the stack trace all I get is a 404, and not the error message that activiti has thrown.

"Basically, why does a direct manual curl command to Activiti return the proper error message, and our subprocess call to activiti does not?"

I' not sure I'm following the use case here, cause there is a lot going on here. But the error is clear:

org.activiti.engine.ActivitiObjectNotFoundException: no processes deployed with key 'CC.FailSubprocess' for tenant identifier 'CC'

There is no process definition with the 'CC.FailSubprocess' id deployed for that particular tenant id.
How does your ACT_RE_PROCDEF look like?

I'm not sure about the subprocess vs curl call … if curl does it right, i would look into the direction of resttemplate.

Thanks for the reply. The ActivitiObjectNotFoundException is expected, we're trying to add some validation to ensure any user that is creating sub processes does so correctly when deploying their BPMN.

I think it may be something to do with the RestTemplate, which I am investigating.
I have also created a python requests call, and I get the full error message back. I would think that is is a deserialization issue and will ask internally about it.

Thanks for the help.

I have figured it out. It was something to do with the rest error handler we've created for activiti .
I've overridden the handleError method(a spring framework method) and thrown an exception with the response body.
This can be considered resolved.

Thanks.
