WHY IS MY MINI FRIDGE LEAKING YELLOW LIQUID HELP?

It’s not leaking water. Only in the morning I saw wet stuff on the floor and it was yellow liquid and some was inside the bottom shelf. Now it’s not leaking no water but the floor is sticky. I have tiny freezer box in the right side and today saw it covered in ice and water on the tray I had dump it in my sink. The liquid was falling from the same right side under the. Bottom silver tray that’s under the fridge. The fridge is fine now but need to keep an eye on it and keep cleaning.
