Say Command In Chat Rcon Command

I want to make a custom command that will make the player execute another command via chat input. Heres the error and command:

    {

        "Teleporting to Outpost"
      ],
      "Permission": "",

From your syntax, it appears that you want the same result as the "NTeleportation" [https://umod.org/plugins/nteleportation] plugin makes possible. If you currently are running that plugin, then there's actually no need to daisy-chain commands through CCC plugin. Just type "/Outpost" and that would teleport your player there, providing you have configured it correctly. I'm not a dev, but maybe that can help your situation.

and btw, the proper syntax to echo a phrase to chat from console/rcon is 

say "What you would like to say in chat"​
