3314735 - Why do I receive the following error 'Invariant Violation: Could not find list type for list' when starting a trigger form in Workflow?

When I am starting a workflow with a trigger form, the following error message is shown: "Invariant Violation: Could not find list type for list". What is the cause?

SAP Signavio Process Governance 3.0

The cause is most probably, that the form contains a field of type list, which itself is coming from Process Manager dictionary attribute of list type. Since there is no possible to construct a list of lists in Process Governance, the error message 'could not find list type for list' appears.

Please delete the respective field from the form and publish the workflow one again.
