Hi CristianJhairT

I tried to reproduce this error and it is because of your wallet configuration, here is how you can resolve this: Step 1: Redeploy Smart Contracts Step 2: Start the client application Step 3: Ensure your wallet is configured to connect to the blockchain network to which you deployed the smart contracts.

Hi CristianJhairT

I faced the same issue and iI updated my truffle version to 5.1.5, cause Truffle v5 versions earlier than 5.1.5 won't successfully compile ^0.6.0 solidity contracts.
