The onValue event in Firebase is not triggering, and I am unable to determine the cause

I am currently working on a web3 application using Next/Js and Firebase. The concept is for users to connect with their Solana wallet, list their NFTs, and choose one to connect in a game-container.

My challenge lies in retrieving information from all connected players listed in Firebase. I want to use this information to create div elements in the game-container displaying all connected players.

Unfortunately, when attempting to fetch a snapshot of all players, the onValue method does not trigger, and I am unsure why...

Nothing seems to be happening, no console logs or error messages.

Below you can find the code snippet related to my database setup:

const database = getDatabase();
const reference = ref(database,'players/' + playerWallet);
const referenceDatabase = ref(database);

function initGame() {

  const allPlayersRef =  ref(database,'players/');

  onValue(allPlayersRef, (snapshot) => { // This block never seems to execute! Why?
    if (snapshot.exists()){
      console.log("Snapshot exists");
    } else {
      console.log("Snapshot is empty");
    }
    console.log("XXXXXXXXXXXXXXXXXXXXXXXXXX");
    // Respond to any changes detected
    console.log("SNAP: "+snapshot.val());
    players = snapshot.val() || {};
    console.log("PLAYERS INFO : "+ players.playerName);

Answer №1

Ensure that the user actually has the proper authorization to access this data. Failure to do so may result in an error message appearing in the console at the point where the code is being executed. Another way to identify potential permission issues is by using the following snippet:

onValue(allPlayersRef, (snapshot) => {
  ...
}, (error) => {
  console.error(error);
});
