Error "AA20 account not deployed" when sending a UserOp with SimpleAccount (Quickstart example)

[guidocazzaniga]

I'm currently using userop@0.4.0-beta.5 with ethers ethClient and walletClient (with viem it is able to build the UserOp)

I'm trying to run the quickstart example from the documentation but it throws the following error when executing both .buildUserOperation() and .sendUserOperation():

Error: could not coalesce error (error={ "code": -32500, "data": { "OpIndex": 0, "Reason": "AA20 account not deployed" }, "message": "AA20 account not deployed" }, payload={ "id": 23, "jsonrpc": "2.0", "method": "eth_estimateUserOperationGas", "params": [ { "callData": "0xb61d27f60000000000000000000000008d5434ca348f8c0b61e2ab9fc1e7119a16b81cdc000000000000000000000000000000000000000000000000000000e8d4a5100000000000000000000000000000000000000000000000000000000000000000600000000000000000000000000000000000000000000000000000000000000000", "callGasLimit": "0x0", "initCode": "0x", "maxFeePerGas": "0xad4adef18", "maxPriorityFeePerGas": "0x3b9aca00", "nonce": "0x0", "paymasterAndData": "0x", "preVerificationGas": "0x0", "sender": "0x2EC95999f509f3F50C977A0D38135276dF00e81C", "signature": "0x48b0982cbf4a28aac976f3ec8270abcf5292b4ebf0814c5aec2944f98d157b555a27003469643c375c7c2f9d3e7e77a2e8993eba7f148ee97d22689363b8f8e41c", "verificationGasLimit": "0x0" }, "0x5FF137D4b0FDCD49DcA30c7CF57E578a026d2789" ] }, code=UNKNOWN_ERROR, version=6.12.2)
