failed examples : batchERC20Transfer & batchTransfer

[jay0xmo]

Thank you for providing various examples, which have been helpful in understanding Abstraction Account. I was able to reproduce other parts successfully, but I am having issues with the implementation of batchERC20Transfer and batchTransfer. When called, I receive the following error message:

{
....
"reason": "Error: VM Exception while processing transaction: reverted with reason string 'account: not Owner or EntryPoint'",
....
}

Upon further investigation, I found that the issue occurs when passing the encodeFunctionData(executeBatch) as a parameter to accountAPI.createSignedUserOp.

erc-4337-examples/scripts/simpleAccount/batchErc20Transfer.ts

Lines 63 to 68 in c7902cb

	const op = await accountAPI.createSignedUserOp({
	target: sender,
	data: ac.interface.encodeFunctionData("executeBatch", [dest, data]),
	...(await getGasFee(provider)),
	});
	console.log(`Signed UserOperation: ${await printOp(op)}`);

within the implementation of accountAPI, the encodeFunctionData(executeBatch) is re-encoded as execute, and this results in an error when execute is called again within executeBatch.

https://github.com/eth-infinitism/bundler/blob/22166ee14b7ea4d017a365fe36cf9d4a49520e6b/packages/sdk/src/BaseAccountAPI.ts#L169-L188

It seems that a modification to the bundler SDK of eth-infinitism is necessary to support executeBatch.
