Hi, on this code i am running into an error: when I am using Alchemy RPC_URL then it gives this error otherwise when I am using ganache there is nothing; Every thing is correct then

Error: could not decode result data (value="0x", info={ "method": "retrive", "signature": "retrive()" }, code=BAD_DATA, version=6.11.1)

below is my RPC_URL but if I am using ganache then there is not any error; all the things are correct then

 RPC_URL=https://eth-sepolia.g.alchemy.com/v2/4yaYwZaOaEmkkyauFaNX6tVY2nkA51aQ

can someone help me?

Hi @MohammadArif13

It looks like you did not deploy your contract on sepolia correctly and you keep trying to call its functions... Make sure you have deployed contract correctly and if yes check if your contract have function retrieve() as currently this function does not for address of contract you are calling

[MohammadArif13]

No it get deploys because it spends some cost of eth from my wallet. Below is the output of my code.

Deploying please wait...

Thanks Bro finally i fixed it after two days by add below line to my code after making contract.

After this line:

 const contract = await contractFactory.deploy()

I add the below line:

await contract.deploymentTransaction().wait(1)

[Nlferu]

Yup so that is what I have mentioned, your contract did not exist because you did not await its creation and that was why issue existed :) Glad its fixed now, cheers!
