+### Error handling
+
+When an error occurs, the component will emit an error event that can be used to handle errors. Example:
+
+```html
+ <adf-start-process 
+      [appId]="YOUR_APP_ID"
+      [title]="'ADF_PROCESS_LIST.START_PROCESS.FORM.TITLE'"
+      [name]="PROCESS_NAME"

+    onError(error) {
+        this.notificationService.showError(event.response.body.message);
