It looks like there is an issue with the address you’re using for your contracts, what is the value of deployedNetwork.address?

Hi @arun_Saketh,

Sorry to hear you are still having issues.

You could look at using OpenZeppelin Network.js for connecting to web3:

Hello :slightly_smiling_face: , i don’t know if this works but you can try :

  • Check if is a delay problem, you can try print in console the deployedNetwork and check after the error if have information

  • Check if this work into async function and put an “await” before you instanciate deployedNetwork
