Solved Inventory Stuffs

Hello everyone!

I am trying to make a /enderchest command. I have made it so that you cannot take stuff out of the enderchest you are viewing, nor put stuff in. I was just testing and I dropped some items out by clicking outside of the inventory space, and this console error popped up:

Console Error (open) Console Error (close)
