Large Command Error with unbalanced brackets [duplicate]

Question

Can't find it anywhere, literally been looking for over 2 hours, i've checked each indivual command and the overall json. Nothing.

Thanks in advance.

Edit: Using MC 1.8.9

Edit 2: This is the error i receive when i put it in a command block and click on any of the four buttons (North, East, South or West):

I Believe I found the issue

When you use tell raw it execute the action as the player, this includes the character limit. I tested it and they both cut off at the same point in the error and when you paste it in chat.
