Fail with error 'Ownable: caller is not the owner'

Question

Hi I am new community member and learning smart contract and trying to develop a forked project.

When I try to migrate my contract to kovan network, I have this error. I am not sure what I am missing or what is wrong but need some assistance about that.

Answer 1

Check your smart contract "owner" property. I believe it's 0x0000...000 which meant you have to use upgradable contract in a right way.
