Request your help regarding Layerzerov2 OApp.

[dmsoltech]

Hi. Hope you are doing great.
Now I am integrating layerzero v2 between Solana and Arbitrum.
I got a question here:
I want to send msg from Arbitrum to Solana, but I can't get it from Solana side despite I can see 'inflight' flag from Arbitrum.
In other words, 'Execute' instruction is not called on the Solana side and lzReceiveAlert Event is also not happening.

I am not sure if this is because of my bad configuration settings or other stuff.

Best Regards
Daniel

@RustChainBuilder could you share "layerzero.config.ts" file along with transaction hash?

If we consider your comment about configuration as a potential issue, we would like to see the 'OApp Configuration' part of your transaction on https://testnet.layerzeroscan.com/.

Actually the configuration for both column should match with each other as in attached screen.

@BZAghalarov Thanks for your reply.

But I don't think that the issue is not Configuration of OApp.

This is the transaction hash that succeed delivered from Arbitrum-Sepolia to Solana-testnet.
As you can see here, executor calls oft's lzReceive instruction.
https://github.com/LayerZero-Labs/LayerZero-v2/blob/main/packages/layerzero-v2/solana/programs/programs/executor/src/instructions/execute.rs
This is the code which is provided by layerzero team. But in this code, executor calls endpoint's lz_receve_alert
it is different between source code and analyzing transaction hash.

@RustChainBuilder I took a look to it but still couldn't find a real reason.

Previous weekend a participated in hackathon and try to use their documentation but there are some missing points there regarding configuration and setting-up OApp. I will try to make article which is describe every points but for now for generating the same issue in my local I will ask what commands did you ran there or which guide you used.
If it is not issue for you I will try to debug it in my local.

@RustChainBuilder You can use lz_receive_types for lz_receive instruction's context.
