Staging test: Listener not resolving - TimeOut Error ( ChainLink Solidity Course)

Question

  Raffle Staging Tests
    fulfillRandomWords
Setting up test...
Setting up Listener...
Entering Raffle...
Ok, time to wait...
All Good here!!!
      1) works with live Chainlink Keepers and Chainlink VRF, we get a random winner


  0 passing (8m)
  1 failing

Problem:

Code runs properly until listener tries to listen to raffle.once("WinnerPicked", async () => { }

• It fails to resolve the try/catch block
• It fails to call upkeep but calls vrf succesfully (transactions for 0.1 ETH registered)

Error:

Error: Timeout of 500000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves.

| When removed alters the code and functionality & does not fix the problem in my case

(bool upkeepNeeded, ) = checkUpkeep("");
      if (!upkeepNeeded) {
          revert Raffle__UpkeepNotNeeded(
              address(this).balance,

I would appreciate if someone could help me figure out how to fix the problem block or code so it runs as originally intended.

Thank you!
