[SOLVED] This user is not allowed to access non-existent class

I try to create new class table using js script

const Moralis = require("moralis/node");

/* Moralis init code */
const serverUrl = "";
const appId = "";
const masterKey = "";


const saveData = async () => {
  await Moralis.start({ serverUrl, appId, masterKey });

  const Monster = Moralis.Object.extend("Monster");
  const monster = new Monster();

  monster.set("strength", 1024);
  monster.set("ownerName", "Aegon");
  monster.set("canFly", true);

  await monster.save();
  console.log(monster);
};

saveData();

Getting error

$ ts-node db/fill_db.ts

/Users/dominik/blockchain/node_modules/moralis/lib/node/RESTController.js:423
        error = new _ParseError.default(errorJSON.code, errorJSON.error);
                ^

You have to use the master key parameter here on this like for .save

You have to use null as first parameter

solved

save need to be made with

await monster.save(null,{useMasterKey:true});

you need to update this in the cods
