The only way to get this error, is if you don't have the blue bikini in your inventory, but there is no way to trigger this scene without having the bikini in your inventory. I guess it's possible to trigger the scene with the console, in which case you need to make sure you have the bikini. If this is the case, add the bikini with the console using the command
"$ inventory.add(jacky_bikini_01)" before you play through that scene.
I guess this maybe could occur through a rollback error, where it drops the bikini, you accidentally roll back, and then it doesn't replace the bikini, and tries to take it from your inventory again.
