Start event form that this version cannot show

The check compat/start-event-form, in the group Engine compatibility.

Error

Why it matters

Before Camunda 8.3 a start event has no form, and from 8.3 the form needs a form id or a linked form that exists.

How to fix it

Set the form id or the form key of the start event, or raise the platform version of the diagram.

Where you see it

The Problems tab lists it under Engine, the editor marks the element on the canvas, and penstock check reports it as compat/start-event-form. It checks the diagram against the engine and the version it is written for: the version in the file's modeler:executionPlatformVersion, or the newest one when the file has none. Operaton and CIB seven are checked as Camunda 7. This check is free.

To turn it off, set camunda-compat/start-event-form or compat/start-event-form to off in your .bpmnlintrc. See Validation.
