mintTo(...) of my Token-2022 - Error processing Instruction 0: invalid account data for instruction

Question

Here's a part of the code of minting my Token-2022 which I've deployed previously

//........................

console.log(
`\npayer: ${payer} $$ ${payer.publicKey}`,
`\nmint: ${mint}`,
`\nsourceTokenAccount: ${sourceTokenAccount}`,
`\nmintAuthority: ${mintAuthority} $$ ${mintAuthority.publicKey}`,
)


transactionSignature = await mintTo(
  connection,
  payer, // Transaction fee payer
  mint, // Mint Account address
  sourceTokenAccount, // Mint to
  mintAuthority, // Mint Authority address
  1_000_000_000, // Amount
  [], // Additional signers
  undefined, // Confirmation options
  TOKEN_2022_PROGRAM_ID, // Token Extension Program ID
);

//Baaaaaaaaaaaaaaaaaaaaaaaaaaaam!!!!

console.log(
  "\nMint Tokens:",
  `https://solana.fm/tx/${transactionSignature}?cluster=devnet-solana`,
);

Error:

Payer has some SOL https://solscan.io/account/4B8dYh439ziBUUWANjGLtAfYeZcwQ7RDEUkNY3qmHZPU?cluster=devnet

as sourceTokenAccount and mintAuthority do too. And you can check them out on solscan too.

Why the error? What's wrong with the arguments?

update

  const owner = Keypair.generate();

  sourceTokenAccount = await createAccount(
    connection,
    payer, // Payer to create Token Account
    mint, // Mint Account address
    owner.publicKey, // Token Account owner
    undefined, // Optional keypair, default to Associated Token Account
    undefined, // Confirmation options
    TOKEN_2022_PROGRAM_ID, // Token Extension Program ID
  );

At https://spl.solana.com/token-2022/extensions#setup there's no clue that it has to be a token account.

It appears to me that the sourceTokenAccount you are using here is not actually a token account, rather, it seems like a normal user account owned by system program.

When you are transferring tokens, you don't transfer tokens to a user's normal account, instead, the tokens are stored in a separate token account which belongs to that user's wallet address. In this case, you would need to create the source token account first.

After digging through transactions a bit, I can see that you did run the CreateAssociatedToken instruction, which created A97rNqFV6PMyMwuKrJw1ysakYHRVHL49kMyQRf7TZN6b as your token account, try putting this in your sourceTokenAccount variable, that should work.
