Hello! I was making a map in which a chain of command blocks should be activated by the testforblock command in the first of them when I press a button on a copper light bulb of my choice. In the chain, a couple of blocks are replaced with the fill command, and then the player's camera is placed in the selected position with the /camera command. But after that there is a block responsible for resetting the camera /camera @a clear. But the reset doesnt work properly and just doesnt work.

Also before /camera @a clear command block i placed command block, that destroy Copper bulb to end cycle! Help pls
