Trivial Pie chart can be created with API without the color field set, but such a Pie chart returns an error in the frontend. This applies to items with Data set type "Item list".
Steps to reproduce:
- Create a Pie chart widget using the API:
- Data set type = 1 (Item list).
- Set no color for an item.
- Open dashboard with this widget.
Result:
The widget is displayed, but shows an unhandled error:
Expected:
Either make such an API call invalid or handle this case and show some default color in UI.
