I have an event management system. Each event has speakers or sponsors. Here, I implement nested resources for Speakers.
When I try to delete a speaker record via the speakers page, I get an error like below.
Filament\Resources\Pages\ListRecords::Filament\Resources\Pages{closure}(): Return value must be of type string, null returned
However, when I delete the record via the edit page, it works without any error.
Here are my codes

How do I make the delete speaker function work?
Solved, by changing Tables\Actions\DeleteAction::make() to
Action::make('delete')
->requiresConfirmation()
->color('danger')
->icon('heroicon-m-trash')
->action(fn (Sponsor $record) => $record->delete())
