Kindly note that you don’t need to give double quotes in the cases. See if that is creating the issue. I can show a snippet of how switch is working
In the below case - It will go to apple case without any error. Also the value in case should be exactly matching including whether it is upper or lower case
In the switch input - the only expected input value is the value given in the case. If matching case is found - it will execute the activities below that case, Else directly execute the activities under default case
