Verifying diamonds with hardhat etherscan-verify results in error

[rayanoncyber]

When using etherscan-verify to verify a Diamond contract, the following error gets thrown for the facet

Error: types/values length mismatch (count={"types":2,"values":1}, value={"types":[{"components":[{"internalType":"address","name":"facetAddress","type":"address"},{"internalType":"enum IDiamondCut.FacetCutAction","name":"action","type":"uint8"},{"internalType":"bytes4[]","name":"functionSelectors","type":"bytes4[]"}],"internalType":"struct IDiamondCut.FacetCut[]","name":"_diamondCut","type":"tuple[]"},{"components":[{"internalType":"address","name":"owner","type":"address"}],"internalType":"struct Diamond.DiamondArgs","name":"_args","type":"tuple"}],"values":["0xB812f503607Ee2259E9607Cb5E5836B550ac6492"]}, code=INVALID_ARGUMENT, version=abi/5.4.1) at Logger.makeError (/Users/rayan/Documents/Cyber/Tech/factory/packages/contracts/node_modules/hardhat-deploy/node_modules/@ethersproject/logger/src.ts/index.ts:225:28) at Logger.throwError (/Users/rayan/Documents/Cyber/Tech/factory/packages/contracts/node_modules/hardhat-deploy/node_modules/@ethersproject/logger/src.ts/index.ts:237:20) at AbiCoder.encode (/Users/rayan/Documents/Cyber/Tech/factory/packages/contracts/node_modules/hardhat-deploy/node_modules/@ethersproject/abi/src.ts/abi-coder.ts:102:20) at submit (/Users/rayan/Documents/Cyber/Tech/factory/packages/contracts/node_modules/hardhat-deploy/src/etherscan.ts:308:12) at processTicksAndRejections (internal/process/task_queues.js:97:5) at async Object.submitSources (/Users/rayan/Documents/Cyber/Tech/factory/packages/contracts/node_modules/hardhat-deploy/src/etherscan.ts:425:5) at async SimpleTaskDefinition.action (/Users/rayan/Documents/Cyber/Tech/factory/packages/contracts/node_modules/hardhat-deploy/src/index.ts:774:5) at async Environment._runTaskDefinition (/Users/rayan/Documents/Cyber/Tech/factory/packages/contracts/node_modules/hardhat/src/internal/core/runtime-environment.ts:217:14) at async Environment.run (/Users/rayan/Documents/Cyber/Tech/factory/packages/contracts/node_modules/hardhat/src/internal/core/runtime-environment.ts:129:14) at async main (/Users/rayan/Documents/Cyber/Tech/factory/packages/contracts/node_modules/hardhat/src/internal/cli/cli.ts:197:5) { reason: 'types/values length mismatch', code: 'INVALID_ARGUMENT', count: { types: 2, values: 1 }, value: { types: [ [Object], [Object] ], values: [ '0xB812f503607Ee2259E9607Cb5E5836B550ac6492' ] } }

If you have a repo, that would help

But at least put the command you use and give the full console output

Thanks

You can find the repo I'm trying to verify here (https://github.com/oncyberio/factory/tree/verification/packages/contracts), I've taken out the deployment script for the first contract as I'm only trying to deploy & verify the second.

I run hardhat etherscan-verify --network rinkeby

`

hardhat etherscan-verify --network rinkeby

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

SO there seems to be 2 different issues
CyberDestinationUtilityFactoryFacet is failing to verify. this could be due to an etherscan bug.

As for the error thrown it is due to the number of arguments in the deployment file not matching the number of arguments the constructor expect.

see https://github.com/oncyberio/factory/blob/65b0ba1be56bc079f61d911b5f78b494143f2cb3/packages/contracts/deployments/rinkeby/DiamondCyberDestinationFactory.json#L5-L43

it expect 2 argument but only 1 was saved here : https://github.com/oncyberio/factory/blob/65b0ba1be56bc079f61d911b5f78b494143f2cb3/packages/contracts/deployments/rinkeby/DiamondCyberDestinationFactory.json#L887

should be fixed in newer version. for existing deployment you can replace the args field with the following:

"args": [
    [
        {
            "facetAddress": "0x35d80a53f7be635f75152221d4d71cd4dcb07e5c",
            "action": 0,
            "functionSelectors": [
                "0x1f931c1c"
            ]
        },
        {
            "facetAddress": "0xc1bbdf9f8c0b6ae0b4d35e9a778080b691a72a3e",
            "action": 0,

            ]
        },
        {
