Next throwing an error that seems to be "Deno not defined"

"use server"

import config from '../config.json' with { type: "json" };

export async function getScores(){
    let scoresPath = `${config.folder}/scores.hth`;
    let scores:{[fileName:string]:number} = {};
    try{
        let data = await Deno.readTextFile(scoresPath);
        scores = JSON.parse(data);
    }
    catch(err){
        console.log("13")
        console.error("Error in scores file: ", err)
        throw new Error("Error reading scores file");
    }
    return {scores: scores, path: config.folder};
}
