Solution to error "attempted index: isRequiresEquippedBothHands of non-table: null" when placing the pump

I saw that multiple people had this problem. So here is my solution. I was using a modded welding mask with cat ears when trying to place the pump. When I changed this mask to a vanilla mask, the pump was placed without problems.
