Based on the documentation, when creating masks in Frigate's web UI, you need to click the first point again to close the polygon(1). The error message "Polygon drawing must be finished before saving" typically indicates that the polygon isn't properly closed, even if the UI shows a checkmark.

To properly create a mask(1):

1. Visit the Web UI
2. Click/tap the gear icon and open "Settings"
3. Select "Mask / zone editor"
4. At the top right, select the camera you wish to create a mask or zone for
5. Click the plus icon under the type of mask or zone you would like to create
6. Click on the camera's latest image to create the points for a masked area. Click the first point again to close the polygon
7. When you've finished creating your mask, press Save
8. Restart Frigate to apply your changes

The key step is ensuring you click the first point again to properly close the polygon before attempting to save(1).

If you're still experiencing issues after following these steps, try:

• Clearing your browser cache
• Refreshing the page and recreating the mask
• Ensuring you're completing the polygon by clicking the starting point

Once saved successfully, your config file will be updated with the relative coordinates of the mask(1).

You may be misunderstanding how object masks work. Object masks are separate from motion masks and zones. In your screenshot, it looks like you are creating an object mask, but you haven't drawn anything on the canvas.

See the documentation: https://docs.frigate.video/configuration/masks/

For anyone else struggling with this, if you're using Brave browser, you need to turn off shields. #12724 Item 14.
