There is the target missing.

@Autowired
private Actions actions;

@ViewComponent
private JmixButton reportButton;

@Subscribe
public void onInitEntity(final InitEntityEvent<Book> event) {
    RunSingleEntityReportAction<Book> action = actions.create(RunSingleEntityReportAction.ID);
    action.setReportOutputName(null);
    **  action.setTarget(this);  **
    reportButton.setAction(action);
}

I have reports with Orders Entity and call it from the orders-detail-view but the system tells me
grafik

Where is the error ?

Kind regards
