$exceptions
$exceptions : array<mixed,\Exception>
The array of exceptions.
This is the deleting failed exception class.
This is thrown if one or more models threw an exception when we tried to delete them. It's important to note that this exception will only be thrown after we've attempted to delete all the saved models. You may access each underlying exception, in the order they were thrown during the whole process, by calling getExceptions to return an array of exceptions.
