Delete patient and family functionality is broken

fsdemo is obsolete. Please test on playground.

I discovered this issue on my local instance. I used fsdemo to give an example only.

I will investigate

Please always specify the exact steps to reproduce the issue. Are you talking about the "Delete" button from the top menu for the patient sheet + selecting "Delete patient and family" from the confirmation dialog?

Thanks for updating the description . I seem to have a similar issue with the [x] buttion next to the pedigree thumbnail on the patient page. If the user chooses "delete family" from the confirmation modal there's no visible effect and an error is printed in the console. Both issues probably have the same cause.
