The API allows to specify a reference for the widget to itself. In the dashboard editing mode, the widget does not display any errors. However, if you try to open the widget settings, this leads to infinity loading of the widget settings menu.

Steps to reproduce:

1. Create an empty template.
2. Use the API request from the attached file, specifying the correct parameters "templateid" of the new template and "auth"
3. Go to the template dashboard setting;
4. Open widget setting menu.

Result:
See screenshot. We don't have any error, but we have infinity loading.

Expected:
Error during API request for creation of the dashboard.
