dev.mod - Error when terminating an instance

[madhurrya]

Getting this error when trying to terminate instances.

I don't get that error for this simple model
https://dev.mod.spiff.status.im/process-models/misc:qa:forms:simple-form-name-age

But it happens for Status models like PP1, PP2, Expense report

Update : This seems to happen in dev.app also

 I can't see the diagrams in 1530 butin 1861, you can fix this error by putting an exclusive gateway before the two inputs to 'Get Name'.

 In 1861 there's no issue with the models. That error happens when terminating the instances. I think something introduced with the latest code.

Elizabeth 1530 and 1861 are not related to the BPMN things I mentioned above :slightly_smiling_face:

 Often models with direct inputs to tasks get this recursion error (I guess it doesn't happen in this case because of the boundary event.
07:58
"Maximum recursion depth" errors are frequently caused by having two inputs to a task without an intervening gateway.

I think the correct thing to do is add a validation in bpmn-js-spiffworkflow telling users that this is invalid. A task cannot have multiple inputs. They must be merged with an exclusive gateway at least.

Also relates to #1368 and #1530

@jasquat Terminate was working fine earlier. This started happening after the latest code update. So it can't be related to a model issue I guess?
It works fine this model https://dev.mod.spiff.status.im/process-models/misc:qa:forms:simple-form-name-age
Issue is with Status models. It was working fine for them earlier. This happens in dev.app also. So not a celery related thing I guess.
