I have not had much success in solving this problem. A contract that does not give errors and that is flattened correctly. Here is the topic:

error Unable to generate Contract ByteCode and ABI

Then we will have to look for another strategy and ask.

What is the correct way to publish and verify a contract from hardhat on a testnet or mainet?
