+*   **guiCheckDatabase**
+
+    Requests a database check, but returns immediately without waiting for the check to complete. Therefore, the action will always return `true` even if errors are detected during the database check.

+    *Sample request*:
+    ```json
+    {
+        "action": "guiCheckDatabase",
+        "version": 6
+    }
+    ```

+    {
+        "result": true,
+        "error": null
