Error while running commands.js

[JulyCrab]

So I get this error when I try to do node commands.js , here's the full log:

C:\Users\"Username"\Desktop\Bot\commands.js:3                                        
  REST, REST                                                                             
        ^

    at node:internal/main/run_main_module:23:47

But when I remove the 2nd "REST" identifier I get this error:

DiscordAPIError[10002]: Unknown Application
    at SequentialHandler.runRequest (C:\Users\"Username"\Desktop\Bot\node_modules\@discordjs\rest\dist\lib\handlers\SequentialHandler.js:198:23)

  code: 10002,
  status: 404,
  method: 'put',
  url: 'https://discord.com/api/v9/applications/CLIENTID GOES HERE, NOT POSTING IT/commands'
}

Please help, I tried finding a solution and can't get to fix it.
