Test Validator SPL Associated Token Account IncorrectProgramId

Question

I'm running a Solana test validator, and I am using spl_associated_token_account::instruction::create_associated_token_account in a transaction to create an associated token account. The transaction creates correctly, and looks like

Transaction {
    signatures: [
        2Y4HFX523xCQqULmxFWCTK3NSUKHBTuHyTjyorDPX4ZDMq12MF1gRVaA7r7DLEZwtXPxdYqekTB7xp6vrwCQUJh7,
    ],
    message: Message {
        header: MessageHeader {
            num_required_signatures: 1,
            num_readonly_signed_accounts: 0,
            num_readonly_unsigned_accounts: 4,
        },
        account_keys: [
            5Xeu3dBDDuiugNvEvo6uN6VvWd37PUTgqFGJPJ32XkmP,
            GNR3TajYA7R3PU6q3SXnecHzgepm999G5TnMaTzKqcoD,
            11111111111111111111111111111111,
            TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA,
            82fDGLz84gDew1qxXVYDcTkEgb146niT6S76xHr1cbYR,
            ATokenGPvbdGVxr1b2hvZbsiqW5xWH25efTNsLJA8knL,
        ],
        recent_blockhash: E4wdTjBTgQh3cyWdX2Uxt97JVTNWr6fKkMyEh6pDKryq,
        instructions: [
            CompiledInstruction {
                program_id_index: 5,
                accounts: [
                    0,
                    1,
                    0,
                    4,
                    2,
                    3,
                ],
                data: [
                    0,
                ],
            },
        ],
    },
}

However, once I send the transaction to the test validator RPC endpoint, I get the following error:

ClientError { request: Some(SendTransaction), kind: RpcError(RpcResponseError { code: -32002, message: "Transaction simulation failed: Error processing Instruction 0: incorrect program id for instruction", data: SendTransactionPreflightFailure(RpcSimulateTransactionResult { err: Some(InstructionError(0, IncorrectProgramId)), logs: Some(["Program ATokenGPvbdGVxr1b2hvZbsiqW5xWH25efTNsLJA8knL invoke [1]", "Program log: Create", "Program 11111111111111111111111111111111 invoke [2]", "Program 11111111111111111111111111111111 success", "Program log: Initialize the associated token account", "Program TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA invoke [2]", "Program log: Instruction: InitializeAccount3", "Program log: Error: IncorrectProgramId", "Program TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA consumed 2392 of 184933 compute units", "Program TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA failed: incorrect program id for instruction", "Program ATokenGPvbdGVxr1b2hvZbsiqW5xWH25efTNsLJA8knL consumed 17459 of 200000 compute units", "Program ATokenGPvbdGVxr1b2hvZbsiqW5xWH25efTNsLJA8knL failed: incorrect program id for instruction"]), accounts: None, units_consumed: Some(0), return_data: None }) }) }

But this doesn't make any sense to me, since the program_id_index is 5, which corresponds to ATokenGPvbdGVxr1b2hvZbsiqW5xWH25efTNsLJA8knL, which is the valid program id for the spl_associated_token_account program.

Is there something I'm missing here?

Edit: context code is

let rpc_client = RpcClient::new(url.clone());
// create fake usdc token
let create_token_tx = Transaction::new_signed_with_payer(
    &[
        system_instruction::create_account(
            &alice_pubkey,
            &token_pubkey,
            rpc_client.get_minimum_balance_for_rent_exemption(
                Mint::LEN
            ).await.unwrap(),
            Mint::LEN as u64,
            &spl_token::id(),
        ),
        spl_token::instruction::initialize_mint(
            &spl_token::id(),
            &token_pubkey,
            &alice_pubkey,
            None,
            6,
        ).unwrap(),
    ],
    Some(&alice_pubkey),
    &[&alice, &TOKEN_KEYPAIR],
    rpc_client.get_latest_blockhash().await.unwrap()
);
// create fake usdc authority account
let create_account_tx = Transaction::new_signed_with_payer(
    &[
        spl_associated_token_account::instruction::create_associated_token_account(
            &alice_pubkey,
            &alice_pubkey,
            &token_pubkey,
        ),
    ],
    Some(&alice_pubkey),
    &[&alice],
    rpc_client.get_latest_blockhash().await.unwrap()
);
println!("{:#?}", create_account_tx);
// fails on the following instruction
rpc_client.send_transaction(&create_account_tx).await.unwrap();

This error is typically misleading. It is actually referring to the program ID of an account's owner. Check that all of your accounts are initialized to the expected program and passed in the correct order
