When using Event listener the rpc call to program function does nothing and eventualy time limit will exceed and test fails

Question

This block of code is giving the trouble..

let listener = null;
    
    //@ts-ignore
    let [event, slot] = await new Promise((resolve, _reject) => {
      listener = program.addEventListener("Deposited", (event, slot) => {
        resolve([event, slot]);
      });
      program.rpc.redeem(
        new anchor.BN(redeemAmount),
        {
          accounts: {
            treasury,
            posMint,
            treasuryVault,
            userVault: userTreasuryVault,
            userPosVault,
            authority: user,
            tokenProgram: TOKEN_PROGRAM_ID,
          },
          signers: [userKeypair]
        });  
    });

the call to the same function without the event listener will execute perfectly fine as I did here:

const tx = await program.rpc.redeem(
      new anchor.BN(redeemAmount),
      {
        accounts: {
          treasury,
          posMint,
          treasuryVault,
          userVault: userTreasuryVault,
          userPosVault,
          authority: user,
          tokenProgram: TOKEN_PROGRAM_ID,
        },
        signers: [userKeypair]
      });

I get no errors other than time limit exceeded.. How do I resolve this..?
