Lesson 9 : 1) Uncaught error outside test suite

[Divyanshu-Madhav]

I'm trying to deploy a smart contract on the sepolia testnet ,so the contract is deployed successfully as seen on the etherscan ,but when im trying to test the contract with staging test by running command hh test --network sepolia
it gives 1) Uncaught error outside test suite

The code is

const { expect, assert } = require("chai")

const { network, getNamedAccounts, deployments, ethers } = require("hardhat")
const { networkConfig, developmentChains } = require("../../helper-hardhat-config")
const { log } = require("console")

developmentChains.includes(network.name)
    ? describe.skip
    : describe("Lottery unit test", async () => {
          let lottery, getEntranceFee
          beforeEach(" test", async () => {
              const { deployer } = await getNamedAccounts()

              lottery = await ethers.getContract("Lottery", deployer)
              getEntranceFee = await lottery.getEntranceFee()
          })
          describe("fulfillRandomWords", async () => {
              it("works with live Chainlink Keepers and Chainlink VRF, we get a random winner", async () => {
                  console.log("Setting up test...")
                  const accounts = await ethers.getSigners()
                  const startTime = await lottery.getLastTimeStamp()
                  let startingBalance
                  console.log("Setting up Listener...")
                  await new Promise(async (resolve, reject) => {
                      lottery.once("winnerPicked", async () => {
                          console.log("WinnerPicked event fired!")
                          try {
                              const lotteryState = await lottery.getLotteryState()
                              const recentWinner = await lottery.getRecentWinner()
                              const endTime = await lottery.getLastTimeStamp()
                              const endingBalance = await accounts[0].getBalance()
                              const entranceFee = await lottery.getEntranceFee()
                              await expect(lottery.getPlayers(0)).to.be.reverted
                              assert.equal(lotteryState, 0)
                              assert.equal(endTime > startTime)
                              assert.equal(recentWinner, accounts[0].address)
                              assert.equal(
                                  endingBalance.toString(),
                                  startingBalance.add(entranceFee).toString()
                              )
                              resolve()
                          } catch (e) {
                              console.log(e)
                              reject(e)
                          }
                      })
                      console.log("Entering Raffle...")
                      const tx = await lottery.participateLottery({
                          value: lottery.getEntranceFee(),
                      })
                      await tx.wait(1)
                      console.log("now time to wait")
                      startingBalance = await accounts[0].getBalance()
                  })
              })
          })
      })

Also the code is passing on the local hardhat testnet successfully
Can anyone tell me where my code is going wrong and what should I do to correct it .
