What went wrong?

deploying a contract using the following:

    strategy_comp_v3 = project.dependencies["strategy-comp-v3"]["master"].Strategy
    strategy_comp_v3 = deployer.deploy(strategy_comp_v3, vault.address, "CompV3LenderUSDC", CASSETV3_ADDRESS, max_priority_fee="1 gwei", max_fee="100 gwei", publish=True)

deploys correctly but it is unable to verify with the following error:

SUCCESS: Contract 'Strategy' deployed to: 0xd0185b3aa44E12015FEbA333660FAb2b8f30dFa0

ContractVerificationError: Compiler data missing from project manifest.

How can it be fixed?

I assume this has to do with how project manifest is dealing with dependencies. If it is a dependency, I guess it should look into .ape/packages/dependency for project manifest
