Diagram fails to open in application (breaks it)

[nikku]

Describe the bug

I try to open the following BPMN diagram and it breaks the application.

I only see a blank screen, and cannot to use the app. Due to the fact that "last opened diagrams" is remembered, I cannot easily recover from this, too.

Steps to reproduce

1. open test diagram
2. observe crash (blank screen)

Expected behavior

• Diagram opens, validation errors (if any) show.

Environment

• OS: Linux, Ubuntu 22
• Camunda Modeler Version: v5.25.0
• Execution Platform: any
• Installed plug-ins: none

Additional context

Questions:

• Why do our existing error boundaries not work, is there something we can improve to prevent such crash?

[nikku]

Root cause:

• When sorting lint errors we assume that either id or name is present on reports, which is not the case if no-bpmn-di reports "missing DI"
• This crashes during sorting

Moving to ready due to impact.

The root cause is fixed in #4518

The error is actually caught in componentDidCatch of App component, but it goes into an infinite loop. My idea would be to have the bottom panel container closed in its own error boundary so that if it crashes, it doesn't take the whole app with it. Not sure if we want to investigate it now tough.
