Help: My cross-chain contract failed when calling the quoteSend transaction.

[ytqaljn]

Hi, I generated an OFT contract according to your Create LZ OApp Quickstart, and then modified the relevant configurations to successfully deploy them to two networks with LZ Endpoint.

Now I successfully called setPeer through my calling script, and isPeer also returned true.

But when I started calling my quoteSend, it returned an error.

Here are the parameters I sent when calling, I am not sure if they are correct:

Here is the error:

Error: missing revert data in call exception; Transaction reverted without a reason string [ See: https://links.ethers.org/v5-errors-CALL_EXCEPTION ] (data="0x", transaction={"from":"0xFd0Cc11A9ffbA29F7db7734b6dc39b1e5212Bb1c","to":"0x42358BE1Ff7964B1eD57897a82071AEE47E38693","data":"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","accessList":null}, error={"reason":"processing response error","code":"SERVER_ERROR","body":"{"jsonrpc":"2.0","error":{"code":-32603,"message":"VM Exception while processing transaction: revert","data":"0x6c1ccdb5"},"id":44}","error":{"code":-32603,"data":"0x6c1ccdb5"},"requestBody":"{"method":"eth_call","params":[{"from":"0xfd0cc11a9ffba29f7db7734b6dc39b1e5212bb1c","to":"0x42358be1ff7964b1ed57897a82071aee47e38693","data":"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"},"latest"],"id":44,"jsonrpc":"2.0"}","requestMethod":"POST","url":"https://rpc.api.moonbase.moonbeam.network"}, code=CALL_EXCEPTION, version=providers/5.7.2)

Can anyone help me solve my problem? Thank you.

[St0rmBr3w]

Did you call setEnforcedOptions? You need to provide at least some execution options either as enforced or extra in order for the quote to succeed. https://docs.layerzero.network/v2/developers/evm/oft/quickstart#message-execution-options

[ytqaljn]

Hmm, I didn't call it, I thought I didn't need to call it if I didn't force extra options. So what value do I need to pass it? If there are no extra options.

Do you mean I need to call setEnforcedOptions? Or do I need to pass a value to the _option field when I call quoteSend?

[ytqaljn]

Hello, @St0rmBr3w

I have now successfully called setEnforcedOptions.

My call parameters are as follows:

But I still get an error when I call _quoteSend later. Below are my calling parameters and the error:

[St0rmBr3w]

You don't need to setEnforcedOptions, but you will need to then pass a bytes array to extraOptions.

The way the OFT Standard works is it takes the _extraOptions, and combines them with the _enforcedOptions to determine the total amount of gas you are requesting on the destination chain.

Look at the line with combineOptions().

function _buildMsgAndOptions(
        SendParam calldata _sendParam,
        uint256 _amountLD
    ) internal view virtual returns (bytes memory message, bytes memory options) {
        bool hasCompose;
        // @dev This generated message has the msg.sender encoded into the payload so the remote knows who the caller is.
        (message, hasCompose) = OFTMsgCodec.encode(
            _sendParam.to,
            _toSD(_amountLD),
            // @dev Must be include a non empty bytes if you want to compose, EVEN if you dont need it on the remote.
            // EVEN if you dont require an arbitrary payload to be sent... eg. '0x01'
            _sendParam.composeMsg
        );
        // @dev Change the msg type depending if its composed or not.
        uint16 msgType = hasCompose ? SEND_AND_CALL : SEND;
        // @dev Combine the callers _extraOptions with the enforced options via the OAppOptionsType3.
        options = combineOptions(_sendParam.dstEid, msgType, _sendParam.extraOptions);

        // @dev Optionally inspect the message and options depending if the OApp owner has set a msg inspector.
        // @dev If it fails inspection, needs to revert in the implementation. ie. does not rely on return boolean
        if (msgInspector != address(0)) IOAppMsgInspector(msgInspector).inspect(message, options);
    }

This is the combineOptions function.

   function combineOptions(
       uint32 _eid,
       uint16 _msgType,
       bytes calldata _extraOptions
   ) public view virtual returns (bytes memory) {
       bytes memory enforced = enforcedOptions[_eid][_msgType];

       // No enforced options, pass whatever the caller supplied, even if it's empty or legacy type 1/2 options.
       if (enforced.length == 0) return _extraOptions;

       // No caller options, return enforced
       if (_extraOptions.length == 0) return enforced;

       // @dev If caller provided _extraOptions, must be type 3 as its the ONLY type that can be combined.
       if (_extraOptions.length >= 2) {
           _assertOptionsType3(_extraOptions);
           // @dev Remove the first 2 bytes containing the type from the _extraOptions and combine with enforced.
           return bytes.concat(enforced, _extraOptions[2:]);
       }

       // No valid set of options was found.
       revert InvalidOptions(_extraOptions);
   }

If you don't setEnforcedOptions AND don't provide an extraOption, you are not passing in any destination gas settings and the call will revert.

[ytqaljn]

Thank you, I have two questions now:

1. You said that you cannot provide a null value to extraOption without setting setEnforcedOptions. I have set setEnforcedOptions now, so I passed 0x to extraOption, but it still reports an error.

2. If I don't set it, can my extraOption pass the sample value in the document: 0x00030100110100000000000000000000000000000000ea60

In addition, the error message I currently receive is not InvalidOptions(_extraOptions) , but Error: call revert exception

@St0rmBr3w Could you please tell me how to solve this error? Or is it a problem with extraOptions?

[St0rmBr3w]

Is there a reason you're passing 0x1 as an input to quoteSend?

[ytqaljn]

@St0rmBr3w There's no particular reason, in fact, I've tried all these different parameters and they all failed.

The value I passed at:
0x00030100110100000000000000000000000000000000ea60

After failing, I passed:
0x

And I have currently set up setEnforcedOptions

[ytqaljn]

@St0rmBr3w
Could you please guide me? I really need your help.

When I called quote after setPeer, I got the same error as yours.This is my script
const feeQuote = await oappContract.quote(toeid, message, false); const nativeFee = feeQuote.nativeFee; console.log("nativeFee is: ", nativeFee);
