Invalid get index 'clothing variant' (on base: null instance') crashing

UnknownUser

I'm new to programming and to godot. I'm was creating my first simple game for a game jam but hit a wall because I was getting a crash that would happen at random. I'm spawning a collection of "babies" into a scene. Each baby will randomly select a clothing item to have on. I'm then creating an array of the babies by looking for the group name babies. I then have three nodes that are supposed to spawn a clothing and set the value of that clothing to match the next baby in the array. When that clothing item is dragged onto a baby it will queue_free() both of the baby and clothing item. While play testing I find that if I switching between selecting different clothing I will accidentally crash the game and i'm not sure why. Below is the code i'm using. Thanks to anyone who can help guide me.

Just to make it a little more readable I'll repost the code with formatting.
