description

When I use an external library, I can deploy a script to link the contract with the external library and deploy it successfully. But it fails when verifying the contract. It should be noted that when I do not use an external library, the verification All are successful.

Etherscan sometime fails to verify when only metadata sources are given. See ethereum/solidity#9573. You can add the option --solc-input to try with full solc-input sources. This will include all contract source in the etherscan result, even the one not relevant to the contract being verified

hmm I can see the libraries field set correctly

can you run verify with --write-post-data and share the result (you might want to remove any ref to your Etherscan api key though)

I didn't modify any output, but the "apikey": "XXXXXX" displayed here is also written in your source code, in the logError function.

Etherscan sometime fails to verify when only metadata sources are given. See https://github.com/ethereum/solidity/issues/9573. You can add the option --solc-input to try with full solc-input sources. This will include all contract source in the etherscan result, even the one not relevant to the contract being verified
