In the process of upgrading from Camunda 7.5 to 7.6 (both community docker images / Apache) we came across numerous workflows that were failing with similar errors in the Catalina logs:
ENGINE-16004 Exception while closing command context: BPMN execution scope expected
Tracking down this error let to it triggering whenever we executed an http-connector service task with an Output Parameter script using inline javascript and attempting to set variables with connector.setVariable(‘someVar’, myValue).
An example script both for a small workflow we were testing with is
var status = connector.getVariable("statusCode");
var response = connector.getVariable("response");
var jsonResponse = S(response);
var documentId = jsonResponse.prop('documentId').value();
connector.setVariable("document", documentId);
connector.setVariable("docStatus", status);
status === 200;
If I comment out the two lines that set the variables, the action completes (but of course that information that was intended for the variables is lost).
Running the tomcat-7.5.0 docker container to roll back to Camunda 7.5 allows the process to complete normally.
Inside the OUTPUT Parameter of the same task now you can set your variables like (assume connector OUTPUT Parameter is named “connectOutputParameter”!)

The workaround from @setu does get the workflow working again. As Stephen mentioned, the same pattern exists across numerous workflows for us, so it would be preferable to find a fix outside of adjusting the models themselves.
I have tried the work-around provided by setu and was able to get it to work. However we have a large number of workflows, each with many service tasks and all of these service tasks attempt to write to process variables. This would be a lot of work to change all of these workflows.
It seems to me that since you have reproduced the bug, that this is a breaking change in version 7.6 and it should be a high priority to fix. Are you able to provide any estimate on when it will be addressed?
This issue is preventing us from running our existing workflows in 7.6 and thus preventing us from migrating to 7.6. Would it be possible to get an estimate of when this issue will be fixed?
We put this ticket in our backlog and after some prioritization it will be implemented, but I am not able to give an estimation when this issue will be fixed. If you need a commitment, I recommend you to become a enterprise customer and to raise a support ticket ;). However, you are always free to submit a pull request to fix this bug in order to speed things up.
Nevertheless, beside the workaround of @setu, a solution would be to define multiple output parameters to set each of the variables without the necessary to use connector.setVariable() inside the script, which is also the intention of output parameters.
