Downloading My World

[ryanelder]

I am wondering how I would download my world, as in play it in single player or send it somewhere else.

-I've tried going to server file manager on the server dashboard, however when i click download on even just one document (and the whole world other tries) it gives me this in a new window:

SyntaxError: Unexpected end of JSON input

    at ValidateController.queryToBody (/home/minecraft-manager/manager/controller/ValidateController.ts:56:42)
    at Layer.handle [as handle_request] (/home/minecraft-manager/manager/node_modules/express/lib/router/layer.js:95:5)

    at ValidateController.verifyUser (/home/minecraft-manager/manager/controller/ValidateController.ts:23:9)
    at processTicksAndRejections (internal/process/task_queues.js:97:5)

I'm also not a special member as in I have just a free account if that would effect anything.

I'm leaving on a mission in a couple days and I wont be able to play or do anything with that world for 2 years so if you good souls of the internet would help spread my concern and help me get a single player world or some other way of saving it. I have a server backup within Mine Hut but I figured I would feel extra secure with my own data storage.
