The "path" argument must be of type string. Received undefined. Failed to verify 1 contract(s)

Question

I'm deploying smart contract to rinkeby network, then trying to verify the contract with

truffle run verify IzoneMember --network rinkeby

but it doesn't work and keep showing this message, however I've installed truffle-verify-plugin, react-script and cucumber.

PS C:\Users\dohva\Documents\Github Repo\NFT\truffle-starter-kit> truffle run verify IzoneMember --network rinkeby

For me, I had my imported contracts as e.g.,

../node_modules/@openzeppelin

I removed the ../node_modules/ and it was fixed
