bad data uri ""

If I click OK without having created a diagram before (via Diagramm editieren) I get the errors bad data uri "" and Failed to handle action: save after saving the page.

Could we hide the OK button in this case?

Or even better: Enter the diagram edit mode when clicking OK and no diagram has been created yet.

A third idea: use a default image like the old drawio plugin if user has not created a diagram.
