Hey @krakxn @alymurtazamemon

Help required !

When I deploy on localhost hardhat , working fine

When I deployed on the rinkeby running scripts, its also fine , but when I do this from frontend side of Next.js it throws this error

Error: Error: cannot estimate gas; transaction may fail or may require manual gas limit [ See: https://links.ethers.org/v5-errors-UNPREDICTABLE_GAS_LIMIT ] (error={"code":-32603,"message":"execution reverted","data":{"originalError":{"code":3,"data":"0x13e7d28d","message":"execution reverted"}}}, method="estimateGas", transaction={"from":"0xB90bA84D4465B8f39e5A5F66E920aB244Da1fb92","to":"0x1a983568b8FC68e296C0B4f08B1c1937e41Db812","data":"0x89bfd38f000000000000000000000000c33147c483e453cf755a672330e021ddaa793de10000000000000000000000000000000000000000000000000000000000000008000000000000000000000000000000000000000000000000016345785d8a0000","accessList":null}, code=UNPREDICTABLE_GAS_LIMIT, version=providers/5.6.0)

I have changed code a lot as working on the enhanced features

Thanks

you can manually set gasLimit to your transaction this way
const tx=await contract.function({value:amount,gasLimit:"250000"})

It's also helpfull but as the I am doing the stuff from frontend side Next.js so it's a bit flummoxed
Thanks

@shoaibshebi add a manual gas like this:

rinkeby: {
  url: process.env.RPC_URL,
  accounts: [process.env.PRIVATE_KEY],
  chainId: 4,
  blockConfirmations: 6,
  gas: 6000000,
},

It helped

It was doing good via scripting but when I try to list NFT from frotend side , caused issue
Actually I was developing a full flexed NFT marketplace , enhancing the Patrick stuff and today its done.
Now you can Sell the NFT only via Clicking the Sell Your NFT button, as I codded all the stuff now.
Blockend is live , just Frontend remaining
Here is the demo:

Hey @shoaibshebi
I'm having the same issue. I did change the gas settings in the hardhat config and redeployed all contratcts. Still getting the same problem. Any ideas?

[shoaibshebi]

Hey
are you getting it by deploying via script or from the frontend side?
adding manual gas actually helped me, please review all the things carefully and try again

thanks
