Initial UserOperation Fails due to initCode in Account Abstraction v0.7

[kishantrikon]

Description:

I am encountering an issue when deploying a smart account wallet using the initCode functionality in the initial UserOperation. Despite following standard practices for generating initCode, I consistently receive errors. Only getting errors with Account Abstraction version v0.7 Previous versions worked without this issue.

Context:

To run the Useroperation I'm Manually deploying the smart account wallet using the SimpleAccountFactory & after that subsequent UserOperations function seamlessly, including paymaster functionalities.

Issue:
The problem persists solely with the first UserOperation that includes the initCode.

Errors Encountered:
From Bundler: "AA20 account not deployed"
Direct Stimulation on EntryPoint Contract: "AA13 initCode failed or OOG" error.

InitCode Generation Process:
const initCode = ethers.utils.hexConcat([ Config.SIMPLE_ACCOUNT_FACTORY_ADDRESS, contract.newsimpleAccountFactory.interface.encodeFunctionData("createAccount", [owner.address, 0]) ]);

The initial UserOperation with initCode should deploy the smart account wallet and allow subsequent UserOperations to function correctly without manual intervention.

I am looking for guidance to resolve this issue. Any help or pointers would be immensely helpful.

It is a little tricky to debug deployment failure.

• try call the factory directly, to see the calldata indeed creates the account
• make sure the verificationGasLimit is high enough, to cover deployment (and validation)
• you can try to use an SDK to create account, instead of directly creating UserOperations.
• If you have further errors, you can ask on the discord channel: https://discord.gg/PVt4dn7zcQ
