Request support on contract usage

[Keith-CY]

Hi team, we(gwscan team) are going to verify the feature of showing data of the target contract on the proxy contract page.

We've deployed a pair of proxy contract and implementation contract but failed to invoke them. An error message

Returned error: {"jsonrpc":"2.0","error":"Internal JSON-RPC error.","id":2866772054041844}

was returned

The source code of contracts have been uploaded at https://gist.github.com/FrederLu/7978291563509a94020afb31cca2f01a

We have checked it but haven't located the error since we're unfamiliar with the proxy contract.

Could you team do us a favor to have a look at the code? Thanks in advance

@Keith-CY Hi, I would like to take a look the failed tx. But I can't find it. Could you please provide a link to to the failed tx?

@magicalne
Hello, when I execute curl following the steps on https://docs.godwoken.io/debug-replay-rpc, no data is found.
Please take a look, the tx is 0x183466fab616eeca6cc4aa605a101b288e6b8743b811fc2d432718148218815e.

curl --location --request POST https://v1.testnet.godwoken.io/rpc/ --header 'Content-Type: application/json' --data-raw '{"id": 2866772054050555, "jsonrpc": "2.0", "method": "gw_debug_replay_transaction", "params": ["0xacf47527fe55114fadc3fc319ecbddb5f9d7203b97b9e39f91237ac787016a02"]}'

{"jsonrpc":"2.0","id":2866772054050555,"result":null}

That's where you need poly_getGwTxHashByEthTxHash.
Before replaying the failed tx, you need to get the godwoken tx hash by eth tx hash:

curl --location --request POST 'https://v1.testnet.godwoken.io/rpc' \
--header 'Content-Type: application/json' \
--data-raw '{
    "jsonrpc": "2.0",
    "method": "poly_getGwTxHashByEthTxHash",
    "params": [
        "0x183466fab616eeca6cc4aa605a101b288e6b8743b811fc2d432718148218815e"
    ],
    "id": 74
}'

Then you can debug the failed tx by sending debug replay rpc with the godwoken tx hash.

I just check the contract log. I cannot tell what's wrong with the contract code.

      "[execute_in_evmone] code size => 1666",
      "[execute_in_evmone] input_size => 164",
      "[handle_message] used_memory(Bytes) => 800",
      "[handle_message] gas left => 2768012",
      "[handle_message] status_code => 2",

status_code = 2, it means evm returned a revert error. That could be anything...
I can see the error happened in the first call of the delegation call. I hope this is helpful.

After adjusting as you said, the RPC is called to get the data, please take a look.
curl --location --request POST https://v1.testnet.godwoken.io/rpc/ --header 'Content-Type: application/json' --data-raw '{"id": 2866772054050555, "jsonrpc": "2.0", "method": "gw_debug_replay_transaction", "params": ["0x7e75ee5be3170f55f838876c60c86fd5efcbb49e3ef16ef601299cc46700d0a6"]}'

Those are debug logs of a successfull tx.

Please take a look my last reply. And how about running this contract on hardhat? Does hardhat throw any error?

@magicalne Thanks for your answer.
Finally, it was found that it was caused by the problem of calling parameters of delegatecall triggered at the contract level.
