Geth Tracing Incorrectly Reporting Signature Error for EIP-7702 Account

[nlordell]

As far as I can tell, the Geth tracing path is not working for EIP-7702 accounts. It does not appear to work for either new, or existing accounts.

Versions

• Geth geth version 1.16.1-stable-12b4131f (latest stable as of writing)
• Bundler aae77140e5c2b1386d04eaeba2d23fc17a62bd87

Reproduce

• Run the bundler yarn preprocess && yarn bundler --network=http://my-node:8545 --tracerRpcUrl http://my-node:8545 --auto
• Submit a user operation from a 7702 account
• Bundler incorrectly reports FailedOp(0,"AA24 signature error")

Note that I am quite sure that the FailedOp error is incorrectly reported - running the bundler in --unsafe mode results in a successful execution of the user op.

---

• If run without the tracerRpcUrl, then the following internal error happens, and an empty message is reported in the JSON RPC response:

}

Note this seems to happen when the EIP-7702 account has not been delegated yet.
