Problem with signing SystemProgram.createAccount instruction after updating Solana mainnet

[wojciech-cichocki]

I have a program deployed on the Solana mainnet. Recently, it seems that the mainnet received an update that included some breaking changes. As a result, I encountered an issue with signing transactions that involve the SystemProgram.createAccount instruction. Let me share the relevant code snippet:

const tx = new Transaction({
  feePayer: payerPubkey
}).add(
  SystemProgram.createAccount({
    fromPubkey: payerPubkey,
    newAccountPubkey: bitmapKeypair.publicKey,
    space: this.program.account.tickmap.size,
    lamports: await this.connection.getMinimumBalanceForRentExemption(
      this.program.account.tickmap.size
    ),
    programId: this.program.programId
  })
);

Here's line of code in the repository: https://github.com/invariant-labs/protocol/blob/master/sdk/src/market.ts#L126

When attempting to sign the transaction, I encountered an error message stating: "invalid program argument".

To rule out any wallet-specific issues, I tested the transaction with other wallets like Backpack wallet and Nightly wallet, and the same error persists.

I've noticed that this issue arises when using the latest dependency version: "@solana/web3.js": "1.78.0".
