Why does my IndexedDB save function not work?

I am making an edge web extension game, I've got the game done, so now i have to do storage. I will use IndexedDB because webSQL will no longer be available soon. I made a save function, but i got an error.

This is the function that calls the save function every 2 seconds:

function init() {
  const data = { 
  money: money, 
  monkey: monkey 
  };
  setInterval(function() {
  saveGameData("myDatabase", "store", data); }, 2000);
}

And this is the save function:

function saveGameData(databaseName, storeName, data) {
  // Open the database
  const request = indexedDB.open(databaseName, 1);
  
  request.onerror = function() {
    console.error("Database error:", request.error);
  };
  
  request.onsuccess = function() {
    const db = request.result;
    
    // Start a transaction and get the object store
    const transaction = db.transaction(storeName, "readwrite");
    const objectStore = transaction.objectStore(storeName);
    
    // Save the data to the object store
    const saveRequest = objectStore.put(data);
    
    saveRequest.onerror = function() {
      console.error("Error saving data:", saveRequest.error);
    };
    
    saveRequest.onsuccess = function() {
      console.log("Data saved successfully");
    };
  };
}

And this is the error i get:

Uncaught NotFoundError: Failed to execute 'transaction' on 'IDBDatabase': One of the specified object stores was not found.

The error is from this line: const transaction = db.transaction(storeName, "readwrite");

It looks like you have missed the onupgradeneeded event. For more information, you can refer to this doc.

If you have already called onupgradeneeded event, try changing the version number.
