ISSUE:

1, Updating product in cart shows "error"

"The product that was requested doesn't exist. Verify the product and try again.": https://i.imgur.com/mDieecL.png 

2, Emptying cart shows "error"

"We can't remove the item.": https://i.imgur.com/NhF4CxJ.png 

SOLUTION:

The module can't get the lastProduct and lastChildProduct from the checkoutSession event at app/code/Bss/Simpledetailconfigurable/Observer/SetAdditionalOptions.php, so getting the product by lastProduct event will cause an error. 

To temporarily resolve the issue, please edit the file: app/code/Bss/Simpledetailconfigurable/Observer/SetAdditionalOptions.php as below:
