dev.mod - "The Data Output was not available in the subprocess output.." error #1563

In dev.mod I am getting this error when running a PP1.

Due to this error can't complete any pp1/pp2 etc

Managed to recreate using this model. https://dev.mod.spiff.status.im/process-models/misc:test:madhurya-testing:temp-group8:temp-model-8-10-call-activity-3

It works without any error in dev.app. https://dev.app.spiff.status.im/i/1417

But it errors in dev.mod https://dev.mod.spiff.status.im/i/38893

If I remove this call activity or changed the process it is calling, then it seems to be working fine.

This seems to happen if the call activity doesn't set the variable is_emp_out. If I do set that variable from within the process that the call activity calls, then the final task data contains the value for that instead of the one set in the Activity_1ev83sg. If the call activity isn't there then it uses the variable set in Activity_1ev83sg.

It seems to be this commit of SpiffWorkflow https://github.com/sartography/SpiffWorkflow/commit/6d18cb8d282b3eaf0a6d10abadf534c663eb45a4. If I downgrade to ac2d8f3f168d7c7cc5d73dfc77b8166f607f379c then it all works.

@essweine any ideas why that would be the case?
