[forge verify-contract]contracts with constructor arguments verified fail

[canu0205]

Hi, I'm trying to verify my contracts. But I got some troubles.

My contract has one constructor argument.

    constructor(address _feeToSetter) public {
        feeToSetter = _feeToSetter;
    }

At first, I tried to verify my contract when deploy it. This is what i used.

forge create --verify --private-key <PRIV_KEY> --etherscan-api-key <ETHERSCAN_API_KEY> src/UniswapV2Factory.sol:UniswapV2Factory --constructor-args "0xAdeb833eee668e50761B4BC8b3Ef476Dc2C86946"

Even if deploying to sepolia testnet was success, verifying contract failed with this error.

And then I tried to verify my contract with forge verify-contract.

forge verify-contract --chain sepolia --etherscan-api-key <ETHERSCAN_API_KEY> 0xDeA279418F5242aD2cE023C2e108FF3D82b19009 src/UniswapV2Factory.sol:UniswapV2Factory --constructor-args 000000000000000000000000adeb833eee668e50761b4bc8b3ef476dc2c86946 --watch

Even If I encoded my constructor arguments, it failed with same error messages.

Can someone show me the way..😂

By reading the docs, you should be doing something like this:

    --constructor-args $(cast abi-encode "constructor(address)" "0xAdeb833eee668e50761B4BC8b3Ef476Dc2C86946") \

Yeah, I knew that abi-encoded constructor argument is needed.
What i did is encoding myself instead of using cast abi-encode.

This command worked for me after I tried some stuff listed below (using Goerli testnet so chain ID = 5)

forge verify-contract --chain-id 5 --constructor-args $(cast abi-encode "constructor(address)" 0xD4a33860578De61DBAbDc8BFdb98FD742fA7028e) --etherscan-api-key $ETHERSCAN_API_KEY 0xe48b24c2AeC6Ef9Cef995c3813cA1084B5Fe9CD8 src/FundMe.sol:FundMe

Possible fixes

1. Try --chain-id 11155111 instead of --chain sepolia
2. Go to terminal and do foundryup then try again.
3. Make sure to refresh your terminal with source .env if you just added a new Etherscan API KEY to it (I forgot this)
4. Try deleting the out folder and try again.
