Error retrieving workflow data.  Invalid workflow instance Id.

We are running Nintex WF 2016 on-prem.


I have a workflow that calls a sub-workflow.  The main workflow run fine, it calls the sub-workflow and executes several actions.  However it errors just before a "Pause for Item Update" action that causes the sub and main workflow to end.


The error in the main workflow is:  Error retrieving workflow data. Invalid workflow instance Id. Workflow Id's must be in the format (xxxxxxx-xxxx-xxxx-xxxxxxxxxxxx).  The error in the sub-workflow is An error has occurred in <sub-wf name>.


I have gotten this error previously.  Republishing the sub-workflow would resolve the error.  But now that "fix" no longer works.  I have not found anything that references this error.


Has anyone else ever see this error?  Any ideas what the cause may be?  (The SharePoint logs don't provide any helpful info.)
