Workflow id initialized to a non-UUID

One of the instances of the workflow was assigned a non-UUID string. It breaks our system because internally in DB we store the workflowInstanceId and our system expects a UUID string. The workflow instance id was the following:

-f42ee415a40ce387734f11185e6fb8ef9337c809cba9414dd5cbdcb897b1991d

NOTE: We are not manually setting the id for this workflow.

No file, test, or entry point is identified in the report. Start by locating where workflowInstanceId is initialized and reproduce the non-UUID assignment; done means the workflow instance receives a valid UUID and a regression test covers the observed case.
