Cannot Edit Expired Maintenance Window in New UI#1434

The new UI presents an error page when I attempt to edit an expired Maintenance Window. I can edit it when using the Legacy UI.

For example, our August Maintenance window just passed. When trying to edit this Maintenance Window I get the “Oopsie” error page.

This needs to be fixed before retiring the Legacy UI.

Hi, there, thanks for reporting. We did notice a few crashes and now they should all be fixed.
