com.adobe.granite.workflow.model.VersionException: Version error retrieving workflow model /var/workflow/models/myWorklowModel

[jeremylanssiers]

We recently deleted the code for this workflow. But it works fine on a local environment and on the development environment, but occurs only on Stage.

[jeremylanssiers · Accepted solution]

We found the cause and solution to this problem. 

The problem occurs when you remove (or rename) a workflow's model. If there is still a running instance of that workflow and the code that removes or renames it gets deployed, a part of Granite UI will crash. 

The solution is to go to JMX, to the Workflows MBean and purge the workflows still running on the old workflow model at http://localhost:4502/system/console/jmx/com.adobe.granite.workflow%3Atype%3DMaintenance

@jeremylanssiers I see this line in the error log snippet that you pasted 

Caused by: javax.jcr.version.VersionException: No such Version: 1.227

So essentially you have workflow instances for a model that doesn't exist.

You should purge any active items using the JMX bean for workflows.
