createMint Throwing TypeError: Cannot read properties of null (reading 'toBuffer')

[arfathyahiya]

Some of the solana packages I've along with their versions @solana/web3.js: 1.94.0 @solana/wallet-adapter-base: 0.9.23 @solana/spl-token: 0.4.6 @solana/spl-token-group: 0.0.3

When trying to use createMint It's throwing me this error

D:\test\node_modules\@solana\buffer-layout-utils\src\web3.ts:17
        const src = publicKey.toBuffer();
                              ^

Code:

import { createMint } from "@solana/spl-token";
const mint = await createMint(
    connection, 
    Keypair.fromSecretKey(base58.decode(secretKey)),
    null,
    null,
    9,
    Keypair.generate(),
    {skipPreflight: true, maxRetries: 2}
);

You're passing null instead of a PublicKey for the third argument.

export async function createMint(
    connection: Connection,
    payer: Signer,
    mintAuthority: PublicKey, // <-- Right here.
    /* ... */
): Promise<PublicKey>
