DB condition
what is the server url?
you can try to reset local dev chain from the legacy interface: legacy.moralis.io
I tried but did’nt work
I created new server, this is the url
https://aym7khsdtaqg.usemoralis.com:2053/server
it looks like that server synced ~5k blocks by now and continue syncing data, maybe you have some configs in hardhat that are trying to sync data from another blockchain?
These are the hardhat configs:
require("@nomiclabs/hardhat-waffle");
require("@nomiclabs/hardhat-etherscan");
require("hardhat-deploy");
require("solidity-coverage");
require("hardhat-gas-reporter");
require("hardhat-contract-sizer");
require("dotenv").config();

Dont know sever is syncing with another blockchain
I humbly told you that when try to deploy this file
const {
frontEndContractsFile,
frontEndAbiLocation,
} = require("../helper-hardhat-config");
require("dotenv").config();
const fs = require("fs");
const { network, ethers } = require("hardhat");
module.exports = async () => {
if (process.env.UPDATE_FRONT_END) {
console.log("Writing to front end...");
await updateContractAddresses();
await updateAbi();
console.log("Front end written!");
}
};
async function updateAbi() {
const nftMarketplace = await ethers.getContract("NftMarketplace");
const basicNft = await ethers.getContract("BasicNft");
fs.writeFileSync(
`${frontEndAbiLocation}NftMarketplace.json`,
//do formate the nftMarkeplace contracts interface/abi code into ethers.utils.FormatTypes.json format
nftMarketplace.interface.format(ethers.utils.FormatTypes.json)
);
fs.writeFileSync(
`${frontEndAbiLocation}BasicNft.json`,
basicNft.interface.format(ethers.utils.FormatTypes.json)
);
}
async function updateContractAddresses() {
const chainId = network.config.chainId.toString();
const nftMarketplace = await ethers.getContract("NftMarketplace");
const contractAddresses = JSON.parse(
fs.readFileSync(frontEndContractsFile, "utf8")
);
if (chainId in contractAddresses) {
if (
!contractAddresses[chainId]["NftMarketplace"].includes(
nftMarketplace.address
)
) {
contractAddresses[chainId]["NftMarketplace"].push(nftMarketplace.address);
}
} else {
contractAddresses[chainId] = { NftMarketplace: [nftMarketplace.address] };
}
fs.writeFileSync(frontEndContractsFile, JSON.stringify(contractAddresses));
}
module.exports.tags = ["all", "frontend"];
using this command yarn hardhat deploy --network localhost --tags frontend
its gives me an error
Error: ERROR processing /Users/apple/Documents/Projects/blockchain/hardhat-nft-marketplace-backend/deploy/03-update-front-end.js:

but with “yarn hardhat deploy” command it works fine and deployed the stuff
Now dont know it deployed where and using what blockchain but the chaindId says its localhost 31337
I am happy that you are helping @cryptokid
it looks like ie has that forking set there
Hmmm
Let me check it, after refining if it works or not
let me catch you back
Thanks btw
Hi Sir @cryptokid
I am in Woooooh condition
You saved me. 
, you listened, you saved me
Thanks a lot Praise to God

I’m also facing the same issue. I restart the Moralis server and hardhat local node as well. Still, I’m not seeing any events logged in the data base.
Server Url: https://xtqqb4chgkvl.usemoralis.com:2053/server
Can you please help?
I don’t see something wrong with that server now, I restarted the server now
I am facing the same issue with my moralis db
its not showing my events . I have tried creating new server but it still not updating my events
this is my sever URL:https://aewqzftsqjdz.usemoralis.com:2053/server
this is my addEvents.js
const Moralis = require("moralis-v1/node")
require("dotenv").config()

const contractAddress = contractAddresses[chainId]["NftMarketplace"][0]
const serverUrl = process.env.NEXT_PUBLIC_SERVER_URL
const appId = process.env.NEXT_PUBLIC_APP_ID
const masterKey = process.env.masterKey
async function main() {
await Moralis.start({ serverUrl, appId, masterKey })
console.log(`Working with contarct address ${contractAddress}`)
let itemListedOptions = {

} else {
console.log("Something went wrong")
}
}
main()
.then(() => process.exit(0))
.catch((error) => {
console.log(error)
process.exit(1)
})
it also doesn’t showing the success condition when creating events on moralis instead it showing else case on my console but it is listing them there after that when I am minting my nft it is not recording the event
@cyptokid can you help me asap
were you able to make it work?
No tried everything still events are not updating
my githubb links
frontEnd: https://github.com/ritesh798/Next-js-Hardhat-NFT-Marketplace-frontend
backend: https://github.com/ritesh798/Hardhat-Nft-Marketplace
.
you could try it on a testnet instead of a local devchain
it should work, we just made it work on another server, double check the contract address and for chain id set “0x539” when you add the event sync
now my code is giving me a new error says "Master Key required for this request " I haven’t changed anything just changed the server and its credentials. I have updated my code with the new server
strange, it is the master key from the same account/server?
is masterKey sent as parameter to moralis.start ?
it now working in my older dapp . things that worked for me is that I changed my chain Id to 0x539
and also I changed table names in the sync script . when I am using the older tables names which were previously synced it is still not working. so change the table names. thanks for your constant support . I hope it helps many developers.
