The dynamic form of the start node cannot be found before the process instance starts

The “/repository/process-definitions/{processdefinitionID}/start-form” interface provided by Flowable-rest cannot find the dynamic form defined on the start node. Is this some kind of bug?

According to the interface source code, Flowable-rest checks to see if the start node defines a formKey. If I only defined a dynamic form on the start node, the interface would not be able to look up the contents of the dynamic form.

Can you provide an example model? If there’s a formKey, this is seen as a hard-coded value, but a regular form is not associated with it.
